Follow-up to #210, which the reviewer correctly rejected: the stated
cause (a sparse column with a stray distant value) doesn't hold, since
the scan already stops at the first empty cell. This is a different,
narrower fix that doesn't change behaviour for any input — it never
truncates a long fill, unlike #210's cap — only how fast a genuinely
long, densely-populated run is scanned.

grid.rs's fill-handle double-click called Sheet::value_ref once per
row to find where the neighbouring column's data ends. Each call does
a band lookup + row lookup + column lookup (three BTreeMap probes) via
CellStore::get. For a real dense run (e.g. a filled column near the
1,048,576-row sheet limit) that's a lot of point lookups on the UI
thread in one frame: ~59ms for a 1,000,000-row run in a release build
(measured with the new fill_handle_perf example), likely worse under
wasm where GridCraft actually runs in the browser.

- crates/model/src/store.rs: CellStore::contiguous_value_run walks
  each band's row BTreeMap with `range` (one in-order pass per band)
  instead of one `get` per row, so a dense run costs roughly one
  tree-traversal step per row instead of one binary search per row.
  Deliberately narrower than `has`/`get`: a stored cell always decides
  the row on its own (even with an empty value), matching what
  `value_ref`'s callers actually test for, not `has`'s "formula counts
  regardless of its cached value" (used for Ctrl+arrow navigation).
- crates/model/src/sheet.rs: Sheet::last_contiguous_nonempty layers
  `spill` back in wherever contiguous_value_run finds no stored cell,
  exactly where plain `value_ref` would fall through to it.
- crates/ui-egui/src/grid.rs: the fill-handle double-click now calls
  this once instead of looping over value_ref.

Result: 999,999-row dense run, 59.2ms -> 24.7ms (2.40x), same answer
(asserted in the example). Four new tests in sheet.rs, including a
300-trial property test against a naive value_ref-loop reference
(spills, formula-with-empty-value, gaps, blanks) — all pass, plus the
full existing suite (`cargo test -p gridcraft-model -p gridcraft-ui-egui
-p gridcraft-engine`; the only failures are #210-era gridcraft-engine
CSV tests already failing on main, unrelated to this change).

cargo fmt reformatted the new example's while-loop condition onto its
own line; clippy's nonminimal_bool caught a negated is_some_and that
reads more plainly as is_none_or.

CI failed with cargo clippy --workspace --all-targets -- -D warnings,
not a test. The actual cause: I'd been validating locally against
rustc/clippy 1.95.0 (the toolchain this machine had installed before
now), while CI installs plain "stable" (1.99.0 as of this run) — two
lints new since 1.95.0 fired there and nowhere in my local checks:

- clippy::int_plus_one on `src.end.row + 1 <= cap` in grid.rs,
  simplified to `src.end.row < cap` (same meaning, no overflow risk
  change: row is a u32 and cap is already saturating-clamped below
  MAX_ROWS - 1, so src.end.row + 1 can't wrap).
- clippy::disallowed_methods on the new fill_handle_perf example's
  three Instant::now() calls — the project's own lint from the time-
  panic fix (#125 history): reading the clock traps on wasm. This
  example is native-only (a `cargo run --release` benchmark, never
  built for wasm), so it gets the same #![allow(...)] perf.rs already
  carries, with the same justification.

Updated the local toolchain to stable (rustup update stable) and
re-ran cargo clippy --workspace --all-targets -- -D warnings clean
before this push, to actually match what CI checks instead of
guessing again.

env! fixes the path to contributors/ when the build script is compiled.
After a checkout is moved or copied, the compiled script keeps looking in
the old location: the About window loses its contributor list, and
because the rerun-if-changed path no longer exists, Cargo reruns the
script and rebuilds the UI crate on every build. Reading the variable at
run time follows the checkout.
view.freezePanes, home.rowHeight, home.columnWidth, the AutoFit, Hide and
Unhide row/column commands and home.defaultWidth always changed the active
sheet: a `sheet` parameter was silently ignored, so a programmatic caller
laying out a sheet that isn't active changed the wrong one, and `Sheet!`
prefixes on `rows`/`cols` were refused as "not a range".

They now take `sheet` (name or index) like the commands that already use
target_sheet, accept a `Sheet!` prefix on `rows`/`cols` (and on Freeze
Panes' `cell`, which was refused), and refuse a prefix that contradicts
`sheet`. The selection belongs to the active sheet, so another sheet needs
explicit lines or a cell. Freeze Top Row, Freeze First Column and Unfreeze
Panes take `sheet` too. Without `sheet`, nothing changes.

home.rowHeight and home.columnWidth take pixels at 96 dpi, the model's unit
(header drags and the Row Height dialog send pixels), but their parameter docs
said points. An agent asking for a 30 pt row got `ht="22.5"` in the file, and
the range check accepted 500 while its message said "between 0 and 409 points".

- The params docs say pixels: `height: 20 (pixels) | points: 15`,
  `width: 64 (pixels) | chars: 8.43`, and `{width: 64 (pixels)}` for
  home.defaultWidth. Pixel values behave as before.
- home.rowHeight takes `points`, Excel's unit (Row Height dialog, `ht` in the
  file), as home.columnWidth already takes `chars`.
- Range errors give the limit in the unit passed: 546 pixels (409.5 points),
  409.5 points, 1800 pixels, 255 characters. `chars` is checked against 255,
  Excel's limit and the widest column a file holds (it went to 256.4 through
  the pixel limit).
- The model's size comments say pixels.

home.conditionalFormat deserialized `style` straight into the model's
Style, so a programmatic caller had to write colours as {"Rgb": 16773836}:
"#FFF2CC", which format_range, colorScale and dataBar take, was refused
with a serde message naming internal types. A key the struct doesn't have
(`style: {preset: …}`, `fillColor`) was dropped, which saved a rule with an
empty format that matches and shows nothing. And a cellIs `value` already
written as a string literal ("\"Closed\"", as in the file and openpyxl)
was quoted again into the text "Closed" with its quotes, so it never
matched.

`style` colours (font, fill fg/bg, borders) may now be "#RRGGBB",
{theme, tint} or "auto", and `fill` may be a colour alone (a solid fill);
a fill colour with no pattern is solid. Unknown keys and a non-object
`style` are refused. A cellIs value that is one string literal is kept.
The model's own shape keeps working.

data.validation {type: "list", formula1: "Open,In progress,Closed"}, which is
how Excel's Source box takes a list, worked inside GridCraft but was saved as
<formula1>Open,In progress,Closed</formula1>. In a file an inline list is a
string literal, "Open,In progress,Closed" (what Excel writes and what our own
reader expects); unquoted, formula1 reads as a formula of names.

- validation quotes such a source when the rule is created, doubling inner
  quotes, using the test list_items already used to tell a literal list from
  a reference or a name (now is_literal_list). A source typed with = (a
  formula), a reference, a name, a sheet-qualified range and an already quoted
  list are stored as before.
- list_items reads a quoted list as a string literal: "" inside stands for
  one quote, so an item with a quote reads back the same after the change and
  from a file.

Creating the rule is the one place that still knows whether the user typed =,
so the XLSX writer is left alone: it can't tell OFFSET(...) entered as a
formula from a literal list, and a rule read from a file is already quoted.

data.validation took any `type`, `operator` or `errorStyle` and fell back
to a default: a typo such as `type: "lst"` saved an "any value" rule
(`type="none"`), which validates nothing, and an unknown operator became
`between`. Each is now an error that lists the accepted values; `any`
stays a type, and the operator aliases (`greaterThan`…) still work.

`style: {fill: "none"}` (or "auto") went through the colour pass and came out as a solid
fill in the automatic colour. `home.fillColor` reads the same word as no fill, so the rule
style does too now.

`{"sheet": null, "cols": "Data!B:B"}` was refused as naming a sheet other than `sheet`,
while `target_sheet` and the cell parameters read a null `sheet` as absent. The prefix now
decides, as it does when `sheet` is left out.

The size box is one frame with the Font name box's fill, border, height and
corners, with the text field and the dropdown arrow inside it (focus shows
the selection stroke). The size list drops directly below the box and is as
wide as it, instead of opening 220 pt wide under the arrow.

home.formatCells documents {style: {numFmt?, ...}}, but the style patch
was merged with the style's snake_case field names, so numFmt (and
borders.diagUp/diagDown) were silently ignored. camelCase keys in the
patch are now renamed to the style's own; snake_case keys still work.
Flash Fill read stored values, so a date was the serial number 45306,
not 2024-01-15: with "15/01/2024" given for 2024-01-15 it found no
part of the source in the example and filled every row with
"15/01/2024" again. It now reads the cells' displayed text, as Excel
does.
After each round, every array formula that was evaluated queued the
dependents of its spill area again, even when it spilled the same area
with the same values. Two arrays that read each other's spill areas
then queued each other in every round, up to the limit of 8: one edit
evaluated 24 formulas instead of 3. An unchanged spill now leaves its
dependents alone. last_recalc_cells counts the formulas of all rounds.
home.insertRows {"rows":"3"} and home.insertColumns {"cols":"B"}
failed with "not a range": only spans such as 3:3 or B:B parsed. The
same went for deleting, hiding, sizing and grouping rows and columns.
A single row number or column letter now means that one line.
MAP, BYROW, BYCOL, SCAN and MAKEARRAY put one value in each cell, but a
LAMBDA returning several values silently gave its first one:
MAP({1,2},LAMBDA(x,{1,2})) was {1,1} and BYROW(…,LAMBDA(r,r)) the first
column. As in Excel, the whole result is now #CALC!, as arrays can't
nest (a single-value array is still fine). MAP with a LAMBDA taking a
different number of parameters than it has arrays, and BYROW or BYCOL
with one taking other than one, ran anyway; Excel gives #VALUE!.
Typing then Right or Down committed through the Enter/Tab path, so Right
continued the run and Down went back to its starting column. Found by
@richard1912 against Excel 365: from B2, type, Tab, type, Right, Enter
lands on D3, and with Down on C4.
`formulas.evaluate` (behind `gridcraft-cli eval` and MCP's `evaluate_formula`) turned any
formula that didn't parse into #NAME?, so `=SUM(1;2)` looked like an unknown function. It now
parses the way `cell.set` does (missing closing parentheses are added) and returns the same
errors: "There's a problem with this formula: expected `,` or `)`, found Semicolon", or the
wrong-argument-count message. An unknown function still evaluates to #NAME?, as in Excel.
The palette every colour menu shares ends with the custom colours last used
(Recent Colors, newest first, ten at most, each once) and a More Colors… button
that opens a picker in the menu: the saturation/value area with its hue bar, egui's
red-green-blue boxes, a hex box (#RRGGBB, RRGGBB, #RGB) with the new colour beside
it, OK and Cancel. OK applies the colour like a swatch and remembers it.

The ribbon's Fill Color and Font Color menus close only on a click outside them or
after a pick, so the picker stays open while it is used; the Format Cells pickers
show it inline. The tab-colour and chart-series menus are sub-menus that close on
any click inside, so they show Recent Colors but not the picker.
A category range two or more columns wide beside a column of values (year beside month, Excel's
multiLvlStrRef) was read as one flat list: 36 rows in two columns became 72 categories, the
series sat in the left half of the plot and the years and months shared one row of labels.
Saving wrote the range as a plain strRef, so Excel lost the two-level axis too.

- gridcraft_core::category_levels: the shape of a category range beside its values (levels are
  columns when the points run down the rows, rows when they run along the columns; up to three
  outer levels), shared by the chart and xlsx crates.
- ChartData.category_levels: the outer levels, nearest the labels first, one entry per category,
  non-empty where a group starts. resolve fills it; a single column is unchanged.
- render: the outer levels in rows under the labels, a group's name centred under its categories
  with a separator at each boundary; in bar charts in columns beside the labels.
- xlsx: <c:cat> written as multiLvlStrRef with the level caches (innermost first), so the axis
  survives a round trip.

Tests in core (shapes), chart (resolve and layout for columns, bars and a row of values) and
xlsx (written XML, read-back, stability, a single column stays strRef). chart-parity, gaps § 4
and the ROADMAP progress log updated.

The cell and header right-click menus, the ribbon dropdown menus and the data
validation pick list drew their items with Button::frame(false), which turns
the background off in every state, hover included. frame_when_inactive(false)
keeps them flat at rest and shows the hover background, as Excel's menus do.

As in Excel, a right-click on an inactive tab now activates that sheet, so
the tab menu's Protect/Unprotect Sheet and Select All Sheets act on the
sheet that was clicked rather than the one that was active.

View > Zoom is now one Magnification column as in Excel: 200%, 100%, 75%,
50%, 25%, Fit selection and Custom with its percentage box. The current zoom
is pre-selected (Custom when it matches no preset), the box shows whole
percentages clamped to 10..400 and typing in it selects Custom. Fit
selection runs view.zoomToSelection with the grid's size, the same answer
as the ribbon's Zoom to Selection. The window is 220 px wide instead of
380; its height is left to the shared dialog sizing work (#978).

Magnification and Fit selection are translated in every catalog.

Column Width, Row Height and the other form dialogs now open with the cursor
in their first field and its value selected, as in Excel: Alt+H, O, W, then
12 and Enter sets the width without clicking into the field first.

- The first text or number field takes focus once it can (a new window's
  first frame is a sizing pass that ignores focus requests), and its value
  is selected so typing replaces it.
- Number fields commit while typing, so Enter or OK in the same frame no
  longer confirms the old value.

Tests: tests/dialog_focus.rs (Column Width and Row Height: type, Enter,
value applied).

insert.slicer and table.insertSlicer looked for the table named by `table` only on the active
sheet. With another sheet active, the call failed with "Select a cell inside a table first, or
pass `table`" although `table` was passed. Other table commands find a table by name in the
whole workbook (Workbook::table).

The named table is now found on any sheet, and the slicer goes on that table's sheet. `at` is
read on that sheet, so "Sheet1!G2" names the table's own sheet. A name that matches no table
gives "no table named `X`".

A formula that reads one later in row-major order (further down, or on a
later sheet) is calculated on demand, inside the formula that reads it.
Each level costs stack, so real models with chains of about 1,000 such
formulas overflowed the 1 MB main-thread stack on Windows and crashed on
open. Past 2,000 levels the chain gave #CIRC! instead.

On-demand evaluation now goes at most 64 formulas deep. A formula needed
deeper suspends the evaluations in progress: it is calculated from the
top, then the suspended ones again, reading the results kept so far.
Chains of any length calculate, with the same results. A suspended
formula read again is a circular reference, as a formula in progress is,
so loops are found at the same cell as before.

Regression tests build the chains in code: 20,000 formulas each reading
the row below, the same hopping between two sheets, a 5,000-formula loop,
and a loop closing into the middle of a deep chain.

Clicking column B's header on a sheet with A2:C2 merged selected A:C,
because selection.set grows every area until merged cells are whole.
Excel leaves header selections alone: column B stays B:B and row 3 stays
3:3. Cell ranges still take merged cells whole (B1:B3 -> A1:C3).

A quick right-click delivers press and release in one frame. The menu
opens at the pointer, and its corner snaps to the nearest physical pixel
(252.46 -> 252.5 on a Retina display), which can leave the pointer just
outside it. The close check then saw that frame's press as a click
outside the menu and closed it right away, so the menu often flashed and
vanished on macOS.

The menu remembers the frame it opened in, and that frame's press no
longer counts as a click elsewhere.

A reference over 16,384 cells was cut to the sheet's used range when it was
read into an array. Next to a full-size operand the two no longer lined up:
SUMPRODUCT(D3:AZ400*B3:B400,(A3:A400=1)*(D1:AZ1=2)) gave #VALUE!,
D3:AZ400*B3:B400 filled with #N/A, and ROWS, COUNTBLANK and --(r="") lost
the blanks past the data. Excel keeps the reference's size.

Bounded references now keep their full shape up to one column's worth of
cells (1,048,576). References that run to the edge of the sheet (A:A,
A2:A1048576, several whole rows) and larger blocks still stop at the used
range, so whole-column formulas stay fast.

A formula read with `cm` (Excel's XLDAPR dynamic-array record in
xl/metadata.xml) now carries `Formula::dynamic`, and the writer keeps the
`cm` and the metadata part for it even when the formula returns one value
and the export shape analysis would not need array evaluation. Before, such
formulas were saved as legacy formulas, so Excel recalculated some of them
with implicit intersection (SUMPRODUCT(IFERROR(range/range,0)) changed
value), and workbooks whose every dynamic formula was scalar lost
xl/metadata.xml altogether.

The mark survives moves, row and column insertion or deletion, sheet and
name renames and LAMBDA call-case fixes; retyping a formula drops it and
the writer decides from the formula's shape, as before. It is serialized
only when set, so saved documents without it are unchanged.

When two dynamic arrays of one recalculation want the same empty cells,
both look free while the pass runs, so formulas evaluated in that pass
read both arrays. The one laid out second becomes #SPILL! at write-back,
but nothing evaluated its readers again, and they kept its values.

With B1 `=SEQUENCE(3)` and A2 `=SEQUENCE(1,3)` (both want B2), a full
recalculation (opening a file, Calculate Now) leaves A2 at #SPILL!, yet
`=A2*10` showed 10, `=SUM(A2#)` 6, and `=C2` and `=SUM(C2:C3)` 3, though C2
is empty. Entering the same formulas one at a time gave the right values.

An array blocked at write-back now sends the formulas that read its anchor
or the area it would have spilled into to the next round, where they read
#SPILL! and empty cells.

Regression test in calc
(`formulas_reading_an_array_that_loses_a_spill_conflict_read_spill_errors`);
it fails without the fix.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
When a dynamic array's anchor gets a new formula, the formula is evaluated
while the old array is still laid out, so it can read the old spilled
values. The anchor was then never evaluated again: it is left out of its
own spill area's dependents, so as not to read its own array.

- `A1` was `=SEQUENCE(3)` and becomes `=SUM(A2:A3)+1`: it showed 6 (2 + 3
  + 1) with A2:A3 empty; recalculating from scratch gives 1.
- `A1` was `=SEQUENCE(3)` and becomes `=SEQUENCE(1,A2+1)`: it read A2 as 2
  and spilled over A1:C1 instead of showing 1.

The anchor is now evaluated again when its old array is gone or partly
freed. It is still left out when its new array covers the old one, where
it would read its own array.

Regression test in calc
(`an_anchor_given_a_formula_that_reads_its_old_spill_area_sees_it_empty`:
the new formula stops spilling, spills elsewhere, or spills over part of
the old area); it fails without the fix.

Adds Language::It ("it", native name "Italiano") with a new per-language
module crates/ui-egui/src/i18n/it.rs, following the existing pattern
(translate(text) -> Option<&'static str>). The catalog has 971 entries:
every key the most complete catalog (pt) translates, plus the PivotTable
Fields pane strings (from es) and Options|Editing. Labels follow Excel's
Italian terminology (Foglio, Cartella di lavoro, Blocca riquadri, Unisci e
allinea al centro, Somma automatica...). Function names are not touched.

Also: it / it-IT / it_CH tags resolve to Italian (system-language default),
Language::ALL and the coverage/tag/age tests include Italian, and
docs/localization-parity.md lists the new language.

Not compiled locally (no Rust toolchain on the author's machine); relying on CI.

In Excel the "contains", "begins with" and "ends with" rules are
SEARCH/LEFT/RIGHT formulas, which fail on an error value, so an error
cell is never formatted by them and always matches "does not contain".
GridCraft matched on the error's display text instead, so #N/A
"contained" a and "began with" #.

Skip error values in the three positive rules and match them in
notContainsText, with a regression test over =NA(), =1/0 and text cells.
OK runs a dialog's command with build_params(&d), which reshapes the
field values for several dialogs (the rule wrapper of cfQuick, the
delimiters list of Text to Columns, the columns of Remove Duplicates and
Subtotal, Data Validation's unused fields, Zoom presets, Series, Define
Name). ui.dialog.confirm passed the raw field values instead, so a
Highlight Cells rule confirmed over the control channel added nothing
and Text to Columns ignored the ticked delimiter.

Make build_params pub(crate) and use it from ui.dialog.confirm, say so
in the control protocol doc, and add tests driving the Greater Than and
Text to Columns dialogs over the control channel.
Larghezza predefinita, Cancella regole dall'intero foglio, Foglio previsione,
Giorno feriale, Singola/Doppia contabilità, Statistiche, Layout rapporto,

edit.autoFill capped source and target at 5M cells separately, but fill()
writes one cell per source lane per step, and it never checked the target
held the source. Whole rows into whole columns (`2:3` into `A:A`) filled
every one of 16,384 columns down a million rows: ~17 billion writes, then
a 24-51 GB allocation abort that catch_unwind can't stop.

Excel (observed via COM on a synthetic workbook) refuses AutoFill when the
target doesn't contain the source or holds it away from every corner, and
accepts any corner-sharing target. edit.autoFill now applies that rule
(fill::holds_source_in_corner), and fill() bounds lanes x steps by
MAX_FILL_CELLS as a backstop. The 5M literals in auto_fill and fill_dir
use the shared constant.

Regression test: fill::tests::autofill_refuses_targets_that_do_not_extend_the_source.

The argument hint, autocomplete, Insert Function and the Formulas-tab menus
read per-language tables of function descriptions and argument names
(i18n/<lang>_functions.rs), keyed by the catalog's English text and
binary-searched. The hint is assembled from the formula syntax's function
name and separator plus the language's argument names, all of them or none,
so it never mixes two languages. Insert Function searches the translated
descriptions and shows readable category names. SPANISH_HELP moves to
es_functions.rs with its 10 functions.
egui's default quit shortcut closed the window without asking to save.
Clear it off macOS (Cmd+Q stays the app's Quit there) and add a regression test.

weekend_mask rejected the all-weekend string outright for both
NETWORKDAYS.INTL and WORKDAY.INTL, but Microsoft documents them as
differing: NETWORKDAYS.INTL "Using 1111111 will always return 0",
WORKDAY.INTL "1111111 is an invalid string". The crate already
implements that split — workday_core's per_week == 0 guard — which was
unreachable dead code while the extra clause stood. Drop the clause:
NETWORKDAYS.INTL counts zero workdays as documented and WORKDAY.INTL
errors through the guard it already has.

The existing test asserted the old behaviour and is updated.
Regression: working_days — on main the NETWORKDAYS.INTL assertion fails
(#VALUE! where Excel returns 0); with the clause dropped it passes and
WORKDAY.INTL is asserted to error.
print_titles read both rows and cols as Options and assigned both
unconditionally, so {"rows":"2:2"} set title_cols = None and
{"cols":"A:A"} set title_rows = None: the repeated rows or columns
disappeared from every printed page with no message, and there was no
way to set or clear just one axis. The sibling pageLayout.pageSetup
already distinguishes "key absent" from "key present but empty"; read
both axes the same way — absent leaves the axis alone, empty/null clears
it, anything else that is not a range is an error rather than a silent
wipe.

Regression test: print_titles_keeps_the_axis_it_is_not_given — on main
the rows-only call clears the columns; with the fix each axis is touched
only when named, an explicit empty value still clears, and a bad range
errors.
The engine's live filter state is always sheet.autofilter — apply_filter,
filter_values, clear_filter, reapply and the slicer command all read and
write it, and a table's header dropdown installs one over the table's own
range — while Table::filter is only ever filled by the reader. Writing
suppressed the sheet <autoFilter> whenever any table merely intersected
it and wrote the table part from Table::filter, which was empty: a
filtered table saved with its rows still hidden and no criteria anywhere,
so on reopen there was no filter to clear and Excel showed an inactive
filter over mysteriously hidden rows. A slicer's selection was lost the
same way.

Fold the coinciding sheet filter's criteria into the table part (colId
offsets are relative to the range's first column, and both ranges start
at the same column, so they carry over verbatim); a filter that only
partially covers a table still has nowhere valid to go and keeps being
suppressed.

Regression test: a_table_filter_criteria_survive_a_round_trip — on main
the table part carries no criteria after a save; with the fold they round
trip, the hidden row stays, and the sheet keeps no duplicate autoFilter.
A cut removed the source's cells and pictures and then re-created the
block's merged areas at the destination and copied its notes there — but
removed nothing from the source, so one merged block became two (an
empty one left behind) and a note ended up on both the old and the new
cell. Excel moves both and leaves the source clean.

The cut now clears the source range's comments, hyperlinks and merges
the same way edit.clear does. A second gap in the same path: paste never
transferred hyperlinks at all, so clearing the source would have lost
them — paste now carries hyperlinks (in What::All and a new
What::Hyperlinks, so edit.pasteSpecial {"what":"hyperlinks"} works
like "comments").

Regression test: a_cut_moves_the_sources_notes_hyperlinks_and_merges —
on main the old merge stays behind and the note is on both cells; with
the fix the merge, note and link all move and the source is clean.
do_sort moved cells, formulas, cell pictures, row heights and floating
object anchors through the sort permutation, and remove_duplicates moved
cells and pictures through the compaction, but neither touched
Sheet::comments or Sheet::hyperlinks (keyed by CellRef): a note that
described one record stayed behind and annotated whatever landed on that
row — 'late payment' on a paid invoice — and a note on a row removed by
Remove Duplicates annotated blank cells. Sheet::comments/hyperlinks are
exactly the range-scoped side data that row and column inserts already
remap and edit.clear already clears, so the omission looks unintended.

Both maps now travel through the same permutation the cells use (the
sort collects before re-inserting, so a swap cannot resurrect an entry
from a destination that is also a source; Remove Duplicates compacts the
kept rows and drops the rest).

Regression test: sort_and_remove_duplicates_move_the_rows_notes_and_links
— on main the note and link stay on their old cells; with the fix they
travel with their record.

The writer gave every drawing its own xl/media/imageN part even when the pictures
had the same bytes, so a workbook with one logo on 16 sheets grew 16 copies of
it on a plain open and save. Out::image_part now returns the existing part when
an identical picture was already written (same extension and bytes), and every
drawing's relationship points to it, as Excel stores a copied picture.

egui copies an owned font's bytes into its text engine (epaint's
blob_from_font_data clones the Cow) and keeps the original FontData too,
so every interface and script fallback font was in memory twice: about
100 MB on a Mac, where the fallbacks alone (Hiragino Sans GB, Hiragino
Sans, Apple SD Gothic Neo, Thonburi...) are 89 MB of files. try_load now
keeps each file it reads for the rest of the run and hands egui borrowed
'static bytes, which it shares. These faces are loaded by every font
rebuild anyway, so keeping them costs nothing, and rebuilds no longer
read them from disk again. A missing or broken file is looked for again
next time. Which faces load, and their order, are unchanged; workbook
fonts (bind_faces) load as before.

Measured on macOS 27 (Apple M3 Max), offscreen snapshot held after its
picture, settled footprint: empty workbook 258 -> 158 MB, the sample
workbook 261 -> 160 MB, a cell in five scripts 258 -> 158 MB; the
rendered pictures are byte-for-byte the same.

Every edit copies the workbook for its undo step (copy-on-write: sheets
and 64-row bands of cells are shared). A floating picture's bytes
(Image.data) and the VBA project (Workbook.vba_project) were plain
Vec<u8>, so each edit on a sheet with a picture, and every edit in a
workbook with macros, kept another full copy of them, up to the 100
steps of the history. They are Arc<Vec<u8>> now, as cell pictures
already are, with base64 helpers for serde (b64::shared, b64::opt). JSON
and XLSX are unchanged.

Measured on macOS 27 (Apple M3 Max), gridcraft-cli, kernel peak
footprint: a 19 MB picture and 50 cell edits on its sheet, 992 -> 22 MB;
10 edits, 215 -> 21 MB.

Floating pictures were decoded at full size, with no limits, into one
process-wide map of textures that never let go, not even when their
workbook closed. Its key was the picture's id and byte length, and ids
are per workbook, so a second open workbook could show the first one's
picture.

The new floating_pictures module, built like cell_pictures, keeps a
cache per egui context keyed by workbook, picture id and size:
- bounded at 128 MB, least recently drawn first, never evicting a
  picture drawn in the last frame, so none turns into a placeholder;
- a workbook's textures go when it closes (checked every frame);
- a picture's header is read first (16,384 px a side, 64 MP at most),
  it is decoded with limits, and to the next size step of what is
  drawn (a power of two or three quarters of one, up to 4,096 px or the
  GPU's limit); it is decoded again only when drawn larger;
- a picture that can't be decoded is remembered, not retried each frame.

Measured on macOS 27 (Apple M3 Max): 12 pictures of 2600 x 2600 opened
from an .xlsx and scrolled through, textures held by egui 258 -> 40 MB,
settled footprint 738 -> 509 MB; after closing the workbook, textures
258 -> 0 MB, footprint 504 -> 236 MB. 24 pictures: textures 490 -> 76 MB.

Excel writes a workbook-scoped defined name in a chart reference as
`[0]!Name`. The reader kept that text, the lexer took `[0]` for a
structured reference, and the series evaluated to #NAME?: a chart over
dynamic (OFFSET) names opened blank with one #NAME? category.

- Read: `[0]!Name` becomes `Name` in c:f (cat, val, xVal, yVal,
  bubbleSize, tx), chartex cx:f and _xlchart names. External books
  ([1]Sheet1!...), quoted sheet names and strings are untouched.
- Write: a bare workbook-scoped name is written back as `[0]!Name`; a
  sheet-scoped name stays bare. A series name that is a defined name is
  written as a strRef instead of literal text.
- Resolve: a series name that is a defined name is evaluated.

Checked black-box in Excel for Windows (Microsoft 365) with synthetic
workbooks: a bare name in <c:f> draws the whole chart blank, without a
repair prompt, for workbook- and sheet-scoped names alike, while
`[0]!Name` and `Sheet1!Name` plot.

- Write: a sheet-scoped name is written `Sheet!Name` (quoted when
  needed) instead of bare; an already qualified name keeps its sheet;
  an undefined name gets `[0]!`. A reference to an unknown sheet is
  kept as written. A qualified series name is written as a strRef.
- Resolve: a series name `Sheet1!Name` is looked up on that sheet, as
  the evaluator does, instead of being shown as literal text.

A workbook GridCraft created had no <fileVersion> in workbook.xml; it now
names GridCraft, and keeps it on later saves.

A workbook read from an Excel file still keeps its <fileVersion> as it was,
appName="xl" included. Observed in Excel 16.114: with the calcFeatures
extension present, Excel uses the saved cell values only when appName is
"xl". appName="gridcraft", "Calc" or no appName makes it recalculate
everything on open, which brings back #799 (lookups into closed workbooks
open as #CALC!). The application that last saved the file is recorded in
docProps/app.xml <Application>GridCraft</Application>, which GridCraft
already writes on every save and which Excel's recalculation ignores.
Fedora keeps each font family in its own package folder, and the cell, serif, mono, Thai and
Hebrew candidates only listed the Debian/Ubuntu/Arch folders, so no cell face was found there and
bold and italic cells drew as regular text in the built-in font. Add Fedora's folders after the
existing Linux entries for each font, as #54 did for the UI fonts, and let mono fall back to
Liberation Mono and then Fedora's default Noto Sans Mono, since DejaVu Sans Mono is optional there.

auto_row_height estimated a line of a bigger font by scaling the sheet's
default row height by size / 11. When the sheet's default already fits
that font, the font counted twice: Excel for Mac saves rows of 16pt text
with defaultRowHeight="21" (28px) and no ht, and opening such a file
fitted every row to 40.7px, 1.45 times Excel's height. Rows mixing Middle
and Bottom aligned cells then looked misaligned.

The estimate now scales an 11pt row's height (DEFAULT_ROW_HEIGHT), so
those rows open at 29px, and rows on a 15pt-default sheet still grow to
their font (#833).

table.resize has existed in the engine since #589/#1706 (overlap checks, tests), and the
command catalog already promised it under Table Design > Properties, but no ribbon button ever
called it -- the only way to resize a table was scripting the command directly (control channel,
CLI, MCP). #935 (no drag handle) assumed this menu path worked; it doesn't.

Adds a "Resize Table" button next to the Table Name field (same Properties group the catalog
already declares), opening a small dialog pre-filled with the table's current range. Confirming
runs table.resize with the typed range, same validation as #589/#1706 (rejects overlap with
another table, matching Excel's "A table can't overlap another table.").

The drag-handle part of #935 is unaddressed; this only restores the menu/dialog path.

Verified manually: created two tables, used the new button to grow one onto the other (rejected),
then to an adjacent non-overlapping range (accepted, table intact).

Copy…, Duplicate, Tab Color, Hide, Unhide…, Protect/Unprotect Sheet,
Select All Sheets), the navigation tooltips (Previous/Next/All sheets,
New sheet), and the AutoSave toggle label and tooltip in the ribbon were

Fix:
- tabs.rs: wrap every hardcoded UI string with app.ui.language.tr(…)
- ribbon.rs: wrap the AutoSave label and hover text with lang.tr(…)
- i18n/cs,de,es,fr,ko,pt,ru,sr,zh: add the 130 missing translation
  entries (each language only gets the entries it was missing)

Translations produced from first-principles per language, following the
terminology used for other sheet/workbook strings already in each file.

Adds Language::Vi (vi), following the per-language module pattern (crates/ui-egui/src/i18n/<lang>.rs). All 398 strings in the master table are covered, checked by the completeness test; vi-VN locale tags resolve to Vietnamese.
Fixed: On macOS, Cmd-click sets mods.command, not mods.ctrl. Both calls therefore pass false for add, so point_header replaces the reference instead of adding a column or row union. Pass mods.command, as the adjacent selection path does. egui defines command as Cmd on macOS and Ctrl elsewhere. (docs.rs)

Fixed:  Point mode remains active when the user changes sheets. The extension closure combines whole-column or whole-row references by coordinates only and discards the previous reference’s sheet. A prior Sheet2!C:C reference can therefore be combined with column E on Sheet3, then emitted as Sheet3!C:E.

Compare the previous reference’s effective sheet with the active sheet before extending it. If they differ, use only the clicked range.

`home.accounting` documents `{range?, symbol?}` but ignored the symbol: the
command always applied the `$` format, so a script or MCP client asking for
lempiras (#1893) or any other currency silently got dollars. The symbol is now
part of the code it writes, and a symbol that would break the format string (a
quote or a backslash) is refused instead of being pasted in. The default is
unchanged, character for character.

Tests: `accounting_format_takes_the_symbol_it_is_given` (displayed text for `L`

The symbol was interpolated with Rust's Debug formatting, which escapes a
control character into literal `\n`-style text. It is now written into the
format's quoted literal directly, and a symbol holding a control character is
refused along with a quote or a backslash, so nothing is escaped behind the
user's back.

### Summary
This change centralizes the translation of user-facing error messages in the UI layer while preserving the original error payloads for machine consumption and AI-agent integrations.

### What changed
- Added a centralized error-translation path in `i18n.rs`.
- The UI now translates only the final display text, instead of altering the underlying engine or protocol error payload.
- If a translated string is not available, the original message is kept as a fallback, avoiding broken or overly-simplified output.
- The translation logic is applied at the presentation layer, not at the source of the error.

### Updated call sites
- Error and alert rendering in `widgets.rs`
- Dialog error presentation in `dialogs.rs`
- Print and feedback failures in `printing.rs`
- Top-level UI error handling in `lib.rs`

### Design intent
- Keep the raw engine errors intact for scripts, control channels, and AI/agent integrations.
- Present a clearer, localized message only to end users.
- Avoid modifying dictionary files or adding new translation entries to the global catalog unnecessarily.
- Keep the behavior consistent with the project’s accessibility and internationalization goals.

### Validation
- The focused i18n test passed successfully.
- The relevant UI test suite passed successfully.
- The repository-required CI gate was run and completed without failures according to the latest verification output.
The in-cell editor ignored Wrap Text: it widened to the text's one-line
width, up to the grid's right edge, so a long wrapped cell became one
unmanageable line while edited. With Wrap Text on it now keeps the
column's width, wraps, and grows down to show every line, as Excel's does.
The multiline field is one row tall at least, not four, so a short edit
doesn't reach over the rows below.
gaps.md §6 still listed four things as missing and function-parity.md still
marked 15-significant-digit comparison as missing, citing #57 — all five
reports are closed and their PRs merged. The work list reads as the place to
pick work from, so a closed entry sends someone after work that is done.

Checked by behaviour, not by issue state, where that was possible:

                                                 with its dependent back to 6

and by their regression tests for the other two:
`deleting_a_3d_span_end_sheet_keeps_the_rest` (#140) and
`sheet_operations_keep_names_on_their_sheets` (#134).

§6 is left open rather than deleted: it says wrong numbers are the worst kind of
bug, and five closed reports are not the same as the category being clear —
that needs §15's oracle suite. The function counts are untouched; this is
formula-language semantics, not the inventory.
`C1#` gave `#REF!` while the dynamic-array formula in C1 happened to return a
single value -- a FILTER matching one row, a SORT or UNIQUE over one item -- so
`ROWS(C1#)` and `SUM(C1#)` failed and `COUNT(C1#)` gave 0. Every formula that
counts or sums a filtered list therefore broke the moment the list had exactly
one entry. In Excel the formula is the anchor of a 1 x 1 range and the three
give 1, the value, and 1.

A pass recorded the spill only for an array larger than one cell:

    if a.rows > 1 || a.cols > 1 {
        self.spills.insert(k, a.clone());
    }

so a 1 x 1 result left no range for `spill_range` to answer with, and `eval`
turned the missing range into `#REF!`. It is recorded unconditionally now.

The report suggested keying this on the cell carrying `cm`, which turned out not
to be expressible: nothing in the model says "dynamic array" positively -- the
reader tells one from a legacy CSE formula only by leaving `Formula::array`
unset. The arm itself is the better test, because a formula whose result is a
scalar never reaches it: `=1+1` does not become an anchor, which a test pins.
It also matches Excel 365, where `=A1:A1` is a 1 x 1 anchor of its own.

A request that waited more than 60 s was answered with a timeout and left in
the queue, so `control::poll` ran it on the next UI pass and dropped the reply.
The client was told its command had failed while the command was applied: an
agent that retried after the error ran it twice, and one that gave up left an
unexpected change in the workbook.

`ControlRequest` now carries who has it -- pending, taken by the app, or
abandoned by its sender -- as the report suggests. `poll` claims each request
and skips one it cannot claim; the connection thread abandons the request when
its reply times out, and says which happened:

  still queued     timed out waiting for the UI (is the window minimised?)
  already started  timed out waiting for the UI, which had already started the
                   request, so it may still finish; its outcome is unknown

The second case cannot be called a failure without guessing. This is the shape
DeckCraft settled on for the same bug (its #719), so the two apps now agree.

Fix: #1914
Adds formulas.selectPrecedents / formulas.selectDependents engine commands
and binds them to Ctrl+[ and Ctrl+] (Ctrl+Shift walks every level), matching
Excel's shortcut parity. Direct-level traces keep whole precedent ranges;
cross-sheet precedents jump to the owning sheet; an empty trace leaves the
selection untouched with an actionable message.
Fixes #1967

With Frame::NONE the text field takes no text margin off its width, so it
wraps at the editor's width less the 2 px inset a side. Measuring 8 px
narrower counted rows the field doesn't have and made the editor reach

The Sort dialog's 'Sort by' box was a free-text field hard-coded to
'A', so sorting a region in column B silently sorted column A unless
the user noticed and retyped the letter. It now seeds from the column
the cursor is in and renders a dropdown of the current region's
columns, labelled with their header text. '+ Add Level' seeds the
next region column instead of a hard-coded B.

It returned an empty string for every workbook, saved or not, so the classic
sheet-name formula `MID(CELL("filename",A1),FIND("]",…)+1,31)` gave #VALUE!:
with no `]` in the string there is nothing for FIND to find. Excel returns
`<folder>\[<file>]<sheet>`, and empty only before the first save.

The model had no file to report. `source_dir` could not serve: it names the
folder relative links to other workbooks are relative to, and must keep naming
it after a Save As into another folder, because the links held in memory are
still written for the old one — only the saved copy is rebased. `source_path`
is therefore its own field, with that distinction written down.

It is set when a workbook is opened, from the path made absolute so the folder
is the one the user sees, and when a full-fidelity save makes a file the
document's own — before the `saved` snapshot, or the workbook would read as
dirty the moment it was saved, and only when it changes, so an ordinary Save
does not clone the workbook for nothing. A workbook that arrived as bytes knows
its name but never a folder and reports `[name]Sheet`, which still splits on the
`]`; an import reports the file it came from, as Excel does. The sheet is the one
the reference is on, not the active one.

CELL is volatile and already in the volatile sets, so a cell holding it answers
from the next recalculation; after a Save As that means F9 rather than the save
itself, which the engine test asserts rather than papers over. Making a save
recalculate is a larger decision than this issue.

`check` still skips CELL("filename") as volatile, as docs/cli.md says: the
cached value in a file is the folder of the machine that saved it.
`SheetProtection` carries eleven permissions. `format_cells` is checked in
`apply_style`, and an edit to a locked cell is caught after the fact by
`check_protection`, but `sort` and `autofilter` had no reader anywhere outside
`sheet_read.rs`, `sheet_write.rs` and a round-trip test: they only ever
travelled through the file. So a protected sheet could still be sorted, and
Ctrl+Shift+L still put an AutoFilter on it.

`refuse_unless_allowed` sits beside `locked_cell_error`, with three call sites:
`do_sort` (which both Sort… and the A-to-Z buttons come through), `toggle_filter`
and `filter_by`.

Where the box decides is worth knowing. Sorting a range of locked cells was
already refused, by the locked-cell guard rather than the permission, because a
sort moves values between locked cells — which is Excel's rule too ("users
cannot sort ranges that contain locked cells on a protected worksheet,
regardless of this setting"). So the Sort box decides for a range that has been
unlocked, while an AutoFilter changes no cell's contents and the box is the only
thing that ever decided it. The test asserts both, and that an unprotected sheet
still sorts and filters.

Not fixed here: Delete Rows and Delete Columns are refused even when their boxes
are ticked, because deleting removes locked cells and trips the same post-hoc
guard, while Insert Rows and Insert Columns work. Letting the guard know which
operation ran is a change to code every command passes through and wants its own
PR.
`cargo xtask ci` has not passed on macOS or Windows since cc21643:

  error: this let-binding has unit value
    --> crates/ui-egui/src/desktop_theme.rs:36:13
  36 |             let mut link = Link::default();

`Link` is the session-bus connection the watcher keeps between reads. Off Linux
there is no bus to keep, so it was aliased to `()`, which makes that binding a
unit binding: `clippy::let_unit_value` reports it and the gate's `-D warnings`
turns it into an error. CI runs Linux only, where `Link` is a real
`Option<Connection>`, so nothing catches it there.

Off Linux `Link` is now a unit struct rather than `()`. The binding has a type,
the lint does not apply, and nothing else changes: `read` still ignores it on
those platforms. An `allow` on the line would also work, but a named type says
what the thing is rather than silencing a lint that only fires on some
platforms.
The deref doc comment still said blocks are trimmed to the used range. Describe
the actual rule: blocks up to FULL_SIZE_CELLS, or up to FULL_SIZE_BOUNDED_CELLS
when they do not run to the sheet's edge, keep their full shape; the rest stop
at the used range. Docs only.

A formula at the nesting limit reading many uncalculated formulas (for
example SUM over a wide range) suspended the abandoned evaluations once per
cell read, restarting them each time. The other formulas read at the limit
are now collected and calculated together with the suspended one, before the

behaviour are unchanged. Adds a regression test (3000 suspensions before, 1

Excel matches LET and LAMBDA names case-insensitively in every script,
so =LET(dług,100,DŁUG*2) is 200. The evaluator compared them ASCII-only
and returned #NAME?. The three lookups (name evaluation, ISOMITTED, a
LET variable shadowing a function name) now fold Unicode case.
- The region already starts at the header row when headers are on, so
  the dropdown label reads start.row for both cases (was showing the
  first data value, e.g. B: 30 instead of B: Revenue).
- + Add Level picks the first region column no level uses yet instead
  of columns.get(levels.len()), which re-seeded an already-used column.

Sheet names starting with '.' or reading as R1C1 (R, C, RC, R1C1...) were saved

along: =1+1+... with 4,096 operands (8,192 characters, exactly Excel's
limit, which Excel accepts and calculates) overflowed the stack when
entered, because the derived Clone of Expr recursed once per operand
down the chain's left spine. Saving hit the same in the XLSX writer.

- Expr: Clone, PartialEq, walk and map follow the left spine in a loop
  and recurse only into right operands and real nesting.
- XLSX: _xlpm. prefixing and the implicit-intersection scan follow the
  spine too. The scan's depth limit of 64 wrote any chain of more than
  about 64 operands as a dynamic-array formula; such sums are plain
  formulas again (ranges in the chain still get array evaluation).
- Evaluate Formula borrows sub-expressions instead of cloning each
  operator's subtree (quadratic memory on a long chain).
- Spanish formula entry and display no longer refuse chains of more
  than 256 operands; the left spine does not count as nesting.

Tests run on a 1 MiB stack (the Windows main thread) with Excel's
observed results: formula (clone/eq/walk/map/adjust at 4,096), calc
(401 and 4,096 operands, -, *, /, ^, &, %, comparisons, 1,500 refs),

A theme's <a:fontScheme> carries latin, ea (East Asian) and cs (complex
script) typefaces for each of the major and minor fonts. The model held
only the latin ones and the writer emitted <a:ea typeface=""/> and
<a:cs typeface=""/> unconditionally, so a Japanese workbook's theme fonts
(e.g. 游ゴシック, MS Pゴシック) were silently deleted on open + save.

Theme gains major_font_ea, minor_font_ea, major_font_cs and
minor_font_cs (#[serde(default)], so older GridCraft JSON still loads;
empty means the file did not set one). The XLSX reader and writer
round-trip them escaped, and a theme without them writes exactly the
empty attributes it wrote before.

Rendering and font resolution are unchanged: the UI does not consume ea
yet, and wiring it in is a follow-up.
xl/sharedStrings.xml can carry phonetic runs (<rPh sb="0" eb="2"><t>ふりがな</t></rPh>)
and a <phoneticPr> beside a string item. GridCraft read only the text and wrote every
string back as <si><t>…</t></si>, so a plain open + save deleted a Japanese workbook's
furigana.

Both are now read — offsets validated against the base text, runs with bad or missing
offsets, sb >= eb or no reading dropped with a warning, and never used to index — and
kept on the workbook as Workbook::phonetics, one entry per string text. The writer
emits them next to the <si> of the same text. The saved table holds each text once, so
two identical texts cannot keep two different readings: the reader keeps the first and
warns. Strings without phonetic data are written byte for byte as before.

Behaviour reference: ISO/IEC 29500-1 §18.4.6 rPh and §18.4.7 phoneticPr (Microsoft
Learn PhoneticRun/PhoneticProperties). Tests: crates/xlsx/src/tests/phonetic_tests.rs

inline strings). Docs: file-format-parity.md, localization-parity.md.
The Japanese catalog still lived inline in i18n.rs with its ribbon and widget
labels, so with the interface set to 日本語 the dialog titles and labels, message
boxes, Backstage/File-view items, template names and native menus showed in
English. This moves it to i18n/ja.rs and adds the 545 keys the Brazilian
Portuguese catalog translates beyond it: 943 keys, the coverage pt-BR has
(~43% of ~2,200 strings), in Excel for Mac 日本語版 wording.

CORE keeps the shared reference set every catalog covers, verbatim and in the
same order (the cross-catalog coverage test still points at it); DIALOGS holds
the new strings, and the lookup checks it first. One test parses pt.rs's source
so the two catalogs cannot drift apart again, one checks that every key is
unique across the two lists and every value is translated, and one spot-checks
the high-value strings.

Docs: the Japanese row and the "Where we are" bullet in
docs/localization-parity.md (943, ~43%), a revision row, the ROADMAP Languages
paragraph and progress log, and gaps.md §11.
The theme watcher (DesktopTheme) reads the desktop's light/dark choice
from the XDG Desktop Portal over a blocking D-Bus call with no timeout.
zbus waits forever by default, so a portal that accepts the call and
never answers stalled the watcher's thread on its first read, and "Use
system setting" stopped following the desktop for the rest of the
session, even after the portal recovered.

The session connection is now built with a 2 s method timeout (REPLY,
shorter than the 4 s POLL). A timed-out call returns InputOutput, which
read() already handles by dropping the connection, so the next poll
asks again on a fresh one.

auto_row_height grew a row for every line break in a cell's text whether
or not the cell wrapped. Excel counts breaks only when Wrap Text is on:
with it off a multi-line value displays on one line and AutoFit gives a
one-line row. A file whose unwrapped cells hold pasted multi-line text
(the shape generating libraries write) opened with tall rows and nothing
visibly tall in them.

The fast path no longer treats a line break as a reason to measure, and
the measuring path lays text out over lines only for a wrapping cell.
Typing a break still turns wrap on (the Alt+Enter rule in cell entry) and
grows the row, as before.

Test: an unwrapped multi-line cell from a file keeps the default height
on open; wrap on grows the row; wrap off returns it; a typed break wraps
and grows. The open-time fit tests from #833 are unchanged.

Save as Web Page wrote only the cell table, so pictures and charts on a sheet
were dropped. A sheet that has either now keeps its own geometry and draws them:

- The table gets the sheet's column widths and row heights (`table-layout:fixed`,
  a `<colgroup>`, a height per row); hidden columns and rows take no room and
  merged-cell spans count only visible lines.
- A picture is an `<img>` with a `data:` URI, a chart is inline SVG built from
  the chart crate's drawing primitives (titles, axes, legends and data labels
  included), each absolutely positioned at its anchor cell plus offset.
- Sheets without pictures or charts write byte-identical HTML.

Adds contributors/people.toml entry for bilalmughal.
The grid's right-click handler never hit-tested objects, so right-clicking
a chart opened the menu of the cell underneath it. And since any button's
drag start grabbed an object, a right press that moved a little started
dragging the chart and no menu opened at all.

Right-clicking a chart, picture, shape or slicer now selects it and opens
its own menu (Delete; for charts also Select Data… and Format Chart
Area…). Only the primary button moves objects.

A data validation alert is the general message box, drawn over the cell
editor, which stays open so the entry can be fixed. The editor read Enter and
Esc first: the first Esc cancelled the edit behind the alert and only the
second closed it, and Enter tried the entry again so the alert came back. The
editor now skips its own key handling while a message is open over it, so Esc
and Enter close the alert (like its OK button). The message box also had the
keyboard focus and didn't give it back, so typing went nowhere until the cell
was clicked; closing it now asks the open editor for focus again.

Numbers stored as text are skipped by SUM and friends, and GridCraft gave
no hint. Like Excel's background error checking, a constant whose text

naming the problem with Convert to Number, which converts every flagged
cell in the selection as one undo step.

  currency, percent, exponent, one parenthesised negative). Dates, times
  and fractions kept as text are not flagged, as in Excel.
- engine: `cmd::formulas::number_stored_as_text(cell)` (constants only,

Korean Excel saves a cell's font under its Korean name (맑은 고딕 for
Malgun Gothic), but the font scan kept one family name per face, the
English one, so those cells were drawn in the default face. Each face now
keeps its typographic and legacy family names in every language, and a
workbook font is bound under the name the workbook uses, which is the
name cell_family looks up. A name two families share goes to the family
whose English name it is, else to the first face by path, so the scan's
directory order no longer decides it. Names bound under two spellings

moved and resized every note box Excel had stored.

Comment gets an optional NoteBox: the <x:Anchor> corners relative to the

si_body returned as soon as no valid run was written, so a shared string with a
<phoneticPr> and no <rPh> — a shape §18.4.8 allows — lost its properties on
save even though the reader keeps them. The runs and the properties are now
written independently: valid runs as before, then the valid <phoneticPr> when
the workbook has one; with neither, the <si> is exactly the plain t_el output.
property_only_shared_string_survives_open_and_save covers read, save and
reopen, and the si_body damaged-data test now expects the property-only output.

The write-time checks the reader also runs (sb/eb clamped into the UTF-16
length, empty readings skipped, type/alignment filtered through the shared
PHONETIC_KINDS/PHONETIC_ALIGNMENTS) were already in the head; the tests above
pin them, so no further change there.

Docs: the .xlsx row and the revision history now state that the shared string
table holds each text once, so duplicate <si> items with the same text but
different readings keep only the first reading (reported as a warning on open),
and that a <phoneticPr> without runs is kept. Both parity docs' "Last updated"
headers match their 2026-10-20 revision rows; the earlier rows keep their dates.
The Japanese catalog's ribbon labels the review flagged are already in the head
("Save (⌘S)" is 上書き保存 (⌘S), "Insert\nSlicer" is スライサーの\n挿入, and the
catalog test asserts the new value), so only the docs needed work: docs/gaps.md
had no revision row for the §11 Japanese-catalog update. Add one dated
2026-10-20, and set the "Last updated" header of ROADMAP.md, docs/gaps.md and
docs/localization-parity.md to the same date as their new rows. Every existing
revision row keeps its original date.
Japanese Excel's B4/B5/B6 are the JIS sizes (257×364, 182×257 and 128×182 mm),
but Page Setup's `b4`/`b5` were the ISO ones (250×353, 176×250): a Japanese B5
worksheet printed 8 mm narrow. `known_paper` now reads `B4`/`B5`/`B6` as JIS and
keeps the ISO sizes reachable as `B4 (ISO)`/`B5 (ISO)`/`B6 (ISO)`. This also
fixes the XLSX round-trip, whose `paperSize` ids 12/13 are the JIS sizes.

Adds the Japanese papers Page Setup lacked: Japanese Postcard (はがき,
100×148 mm), Japanese Double Postcard (往復はがき, 148×200 mm), Japanese
Envelope #3/#4 (長形3号/4号, 120×235 and 90×225 mm), Japanese Envelope Kaku
#2/#3 (角形2号/3号, 240×332 and 216×277 mm), A6, and aliases such as
`postcard`, `chou #3`, `kaku #2`; the xlsx paper table gains ids 42 (ISO B4) and
43/69–74/88 so these names survive save and reopen (the ISO B5/B6 names have no
ECMA-376 paper id and stay engine-side).

The pageSetup/pageLayout.size parameter docs list the names, the Page Layout
Size menu lists them, and tests pin the point sizes, the PDF MediaBox for A4
(unchanged), B5, postcard, double postcard and kaku #2, landscape and
fit-to-page, the unknown-name Letter fallback, and the XLSX round-trip.

Docs: docs/target-app-parity.md print row + revision history, and ROADMAP.md
progress log, dated 2026-10-21.
長形4号 is a 90×205 mm envelope (90×225 mm is 長形40号, a different one), so
the paper table gave it a height 20 mm too tall — and XLSX paper id 74, the PDF
MediaBox and the print preview all followed it. Use 205 mm (581.10 pt) and pin
the corrected size with a dedicated assertion; the ROADMAP progress row is
corrected too. 長形40号 is not added: it is a different envelope.

The Page Layout ▸ Size menu stopped at `B5 (ISO)` and never offered
`B6 (ISO)`, which the engine and the command docs support; add it.
The pane ran `pivot.fields` on every frame while the active cell was in a
PivotTable report. That command reads the whole source list and collects
distinct labels for every field, so a 250,000 x 20 source made each frame
cost ~2.4 s and the window looked frozen (#2113).

Keep the answer in GridState, keyed by (doc uid, revision, pivot), the way
Page Break Preview keeps its pages. Any undoable edit, undo or redo bumps
the revision and drops it.

Known limit: Calculate Now / Calculate Sheet don't bump the revision, so
volatile formulas in the source can leave the tooltip samples stale until
the next edit; the field list itself only changes through undoable edits.

VERIFIED
- New test pivot_fields_pane_reuses_its_field_list_until_the_workbook_changes
  fails without the change and passes with it.
- Release build, 250,000 x 20 synthetic source, pane open (ui.inspect):
  main ~2,400 ms per frame throughout; this branch 2,528 ms for the first
  frame, then 0.4-0.9 ms.
- `cargo xtask ci` passes all 8 steps on macOS with the separate clippy
  fix from #2141 applied locally (main fails clippy on macOS without it).

NOT IN THIS CHANGE
- The report is still empty after opening a file saved with
  refreshOnLoad="1" (second part of #2113).
- `pivot.fields` itself is unchanged; the first frame still pays one scan.
LINEST, LOGEST, TREND and GROWTH built k x k normal-equation matrices
(plus two copies in sym_inverse, O(k^3)) with k taken straight from the
known_xs shape, so one formula could allocate gigabytes and abort on open.
More than 255 predictors is now #VALUE!, and more than 1e9 rows x k^2
multiply-adds is #NUM!, both checked before any allocation.

Every area, array and value of one SUBTOTAL/AGGREGATE call is charged against MAX_CELLS before any cell is read; past it the call returns #NUM!. A value stored in XFD1048576 no longer makes SUBTOTAL(9,A:XFD) read ~17 billion cells into a vector.

Parenthesised negatives were parsed by recursing once per level, so runtime
text such as REPT("(",32767)&"1"&REPT(")",32767) overflowed the stack. Strip
the parentheses in a loop, toggling the sign per level; results are unchanged.

zip2 (binary operators, TEXT), zip3 (array IF) and MAP now compute the
broadcast cell count with checked multiplication and return #NUM! when it
exceeds MAX_CELLS, instead of allocating (abort) or wrapping on wasm32.

Clipboard HTML is read only as far as the pasted text's shape (clamped
to the sheet) and at most 1,000,000 cells; colspan/rowspan are clamped
to the sheet extent before expanding, and rowspan now keeps later rows
in their columns.

stops. Docs corrected; tests cover a style-only stored cell over a spill
value.
