An independent review of the table found two meaning errors:
"Enter" is both the status-bar mode and the tooltip of the confirm
button next to the formula bar, so "Zadat" fits both places better
than "Zadavani"; "Convert to Range" uses "oblast" (as "Oblast tisku"
does), not "rozsah".

Czech joins Russian under "other shipped languages" in ROADMAP.md and
docs/localization-parity.md: 266 ribbon labels (~12%), menus only,
formulas still en-US. Timestamp lines and revision history updated.
Kept separate from the catalog so it can be dropped if the docs are
refreshed upstream.

- The catalog-completeness test requires a non-empty Czech label for
every key of the reference (Japanese) table.
- Czech context keys: `Page Layout|Orientation` and `Orientation` get
different labels; unknown text such as `Sheet1!A1` passes through.
- `cs-CZ` / `cs_CZ.UTF-8` system tags and `parse("cs")` resolve to Czech.
- The ribbon renders after switching to Czech, and the choice persists
in UiState.
- Czech keeps canonical formula entry (`=SUM(1.5,2.25)`), and `=SUMA(1;2)`
is not accepted.
- The UI font draws every Czech accented letter, upper and lower case,
without tofu; Czech shares the default Han font order.
Czech spells "Data" as English does, so the Czech checks probe
"Formulas" -> "Vzorce", where an English fallback would be caught.

Add a Czech table with all 266 interface labels (the same key set as
Korean, Russian, Simplified Chinese and Brazilian Portuguese) and
register `cs` in Language: name "Čeština", code `cs`, system tags
`cs-*` / `cs_*`, appended to the end of the switcher. The language
command help, its error text and the snapshot example usage list `cs`.
Like the other ribbon tables, it covers the ribbon, sheet tabs and
widgets; dialogs, menus and messages stay English. Formulas stay
canonical English: Czech uses the English formula locale like every
non-Spanish language.
Translated from the meaning of each English label (clean-room, not from
another product's localization), with AI assistance.

View › Page Layout (and the status-bar button) now shows the sheet as printed
pages on a desk instead of overlaying page outlines on the grid.
- Model/XLSX: per-sheet view mode (normal / pageLayout / pageBreakPreview),
saved as <sheetView view="…"> and read back. view.* commands set it per
sheet ({sheet?}) without an undo step or dirtying a clean workbook.
- Engine: paper::PageGrid paginates the sheet from A1 with the print
pagination (print::split_bands, shared with PDF export and printing) and
maps cells to pages and back; header/footer section helpers
(split/join, &[Page] field names) shared with the PDF header code.
pageLayout.headerFooter takes {part, section, text} for one section and a
sheet; header/footer strings are capped at 255 characters.
view.ruler toggles the rulers.
- UI: Geo carries the page grid, so painting, hit-testing, selection,
editing, objects and scrolling work through the page transform; frozen
panes are ignored in this view. Pages with margins and gaps, "Click to add
data" pages, rulers in inches (English) or centimetres, headers/footers
drawn on printed pages, click a margin section to edit it in place; a
click elsewhere commits (one undo step), Escape cancels. Header & Footer
contextual tab: presets, Page Number, Number of Pages, Current Date/Time,
File Path, File Name, Sheet Name, Go to Header/Footer. View › Ruler.
- New strings in every catalog; new code-drawn icons; desk colour token.

Pass-through of package content GridCraft does not model: on read the raw
parts are kept with their content types and relationship graph per owner
(package root, workbook, sheet); on write they get fresh part names where
needed and new relationship ids, and the r:ids in kept XML are rewritten.
Kept: custom document properties, ribbon customisation, add-in task panes,
custom XML, links to external workbooks with <externalReferences> (never
followed), connections, sheet query tables, printer settings with the
<pageSetup r:id> (#324), form and ActiveX controls, OLE objects and sheet
backgrounds with their VML shapes (merged with GridCraft's note shapes).
Content whose graph reaches parts GridCraft rewrites is dropped with a
warning; sheet content goes with its sheet and is not copied by Copy Sheet.

Clicking the File tab now opens a full-window Backstage view in place of the
ribbon, formula bar, grid and sheet tabs, like Excel's. Esc or the back arrow
return to the sheet. Pages: Home (new + recent), New (blank + samples), Open
(recent + Browse), Info (location, properties, Protect Workbook), Save, Save As,
Print (page preview, scope, fit to page, Page Setup), Export (PDF, CSV, web
page), Close and Options (theme, language, formula bar, AutoSave, calculation).
Every action runs an existing command or dialog.
Adds `file.options` (reports the workbook's calculation settings and asks the
interface for the Options page) and the UI command `ui.backstage {page}`.
Keyboard shortcuts and the macOS native menu are unchanged.

data.solver maximises, minimises or targets a value in an objective cell by
changing variable cells under <=, >=, =, int and bin constraints. Simplex LP
linearises the model through recalculation, checks linearity and solves it

AppKit draws the traffic lights centred in its standard 28 pt title-bar
band, but GridCraft's title bar was 38 pt tall, so the lights sat above

and content starts after the lights with the same gap they keep from the
top. Other platforms are unchanged.

Audited the grid, ribbon and editor key handling against Microsoft's
published Windows and Mac shortcut lists. New keymap.rs binds the ones
whose feature already exists: Ctrl+Shift+~!@#$%^&_ number formats and
borders, Ctrl+2-5, Ctrl+Shift+: time, Ctrl+' / Ctrl+Shift+" from the cell
above, Ctrl+L, Ctrl+Shift+L, Ctrl+P, Ctrl+Alt+V, Alt+=, Alt+Down,
Alt+Page Down/Up, Ctrl+Shift+Home/End, Shift+Home, the F-key family
(Shift+F2/F3/F9/F10/F11, F5, F7, F12, Ctrl+F1/F3/F4, Alt+F1, Ctrl+Alt+F9)
and the Excel for Mac variants (Cmd+L/E alignment, Control+E Flash Fill,
Cmd+Option borders, Cmd+Shift+K/J/H/R). Number-format keys match the
physical key; AltGr text never triggers a Ctrl+Alt shortcut. Fixes the
command catalog's wrong shortcut labels and documents the audit.

The theme could only be chosen in the View tab's Display theme box, and
the app always started light. Now:
- a title-bar button switches light/dark in one click (view.darkMode);
right-click offers System / Light / Dark;
- File › Display theme offers the same three (Excel keeps it under
File › Account › Office Theme);
- the desktop app follows the system appearance until a theme is chosen
and saved in ui.json (UiState's default stays light for tests).

AccessKit's macOS adapter subclasses the window's content view and
restores its class when the window is torn down; AppKit's Touch Bar
support observes that view via KVO, so the next display cycle throws in
-[_NSTouchBarFinderObservation invalidate] and the quit ends in a crash
report. On macOS, on_exit now exits right after saving the preferences,
before eframe drops the window (what eframe itself does without
run_and_return). Same fix as storytold/vectorcraft#670.

Enumerating Vulkan adapters crashes inside Intel's igvk64.dll on some UHD
Graphics drivers, before any Rust error handling runs. Since #22 the
Windows instance is DirectX 12 only; this keeps Vulkan out of every
default path and adds two fallbacks so DX12-only can't leave a PC without
a window:
- A DirectX 12 probe before eframe starts: no hardware adapter that meets
eframe's limits -> OpenGL (plus DX12/WARP as last resort when WARP is
all DX12 offers).
- If run_native fails with a wgpu error before the app was created, start
once more with the other of DX12/GL (eframe reuses its event loop).
WGPU_BACKEND still overrides everything, and nothing else is tried then.

Sheet Right-to-Left (view.rightToLeft, XLSX rightToLeft) was stored and
round-tripped but never rendered. The grid now lays out in logical
left-to-right coordinates and mirrors on screen: painted shapes are
reflected (text and pictures only moved), floating objects move as a
whole, pointer input is mirrored back for hit-testing, Left/Right arrows
follow the screen, and the cell editor, text box editor, popups and the
vertical scrollbar are placed on the mirrored side. Page Layout gets a
Sheet Right-to-Left button.

Like Excel for the web, a bar in the upper part of the column-header strip
and one in the left part of the row-header strip sit on the frozen panes'

through view.freezePanes; dragging back to the corner unfreezes.

- Model: Sheet.edit_ranges (title, ranges, optional password hash,
security descriptor) and gridcraft_model::password: the ECMA-376 legacy
16-bit hash and the salted, iterated SHA-2 hash (SHA-512/384/256; other
algorithms, damaged hashes and spin counts over 10,000,000 are refused).
New passwords use SHA-512, spin count 100000. Adds the sha2 crate.
- XLSX: <protectedRanges> read and written; an unreadable password keeps
the range locked.
- review.allowEditRanges {action: list|add|modify|delete|unlock, ...}: empty
params list; ranges can't change while the sheet is protected; unlock
verifies the password for the session. Not journaled (passwords).

comments (thread, replies via parentId, done for resolved, dT when known)
and xl/persons/person.xml (one person per author), with the [MS-XLSX]
relationship and content types. Each thread keeps its legacy note, linked
by the tc={id} author and xr:uid; its body is the text plus replies.
Ids are GUID-shaped and deterministic.
- Reader: keeps dT timestamps (Comment.dates, JSON-compatible), drops
replies whose thread is missing, and reads note visibility from the VML
<x:Visible/> (best effort, broken VML skipped silently).
- Invalid dates are never written. Round-trip and hostile-input tests.

The ribbon button inserted a column chart straight away. It now opens an
Insert Chart dialog: a Recommended tab (insert.chartRecommendations, a
heuristic over the data's shape: series, points, labels, negatives) and an
All Charts tab, each with a live preview of the chart for the selection.
OK inserts the chosen type and selects the chart.
insert.recommendedCharts stays dialog-free for programmatic calls: without
a type it inserts the first recommendation; type/subtype pick one.
insert_chart is split into build_chart (also used for previews).

UI fonts such as Noto Sans, Cantarell and egui's built-in Ubuntu lack some

The file format has no `@` operator, but formulas with an explicit
implicit intersection were written with a literal `@`
(`<f>@A1:A3*2</f>`). Excel writes `@x` as `_xlfn.SINGLE(x)`, which only
dynamic-array formulas carry. The writer now does the same and marks such
formulas cm="1"; the parser reads `SINGLE(x)` back as `@x`, as it already
does for `ANCHORARRAY` and `#`.
Two cases in the #83 metadata test expected a redundant `@` (`SQRT(@A1:A3)`,
`@A1:A3*2`) to be written as an ordinary formula. Dropping the `@` there is
only lossless if the reader puts it back on legacy formulas, which it
doesn't yet (the read side of #64), so they now expect cm.

Turning the filter on with a multi-cell selection used the selection as the
filter range. With only the header row selected, the filter had no data rows:
the dropdown list was empty and filtering hid nothing. A one-row selection
now extends down over the current region below it. An explicit `range`
parameter is still taken as given.
The filter menu gets a search box, as asked for in the issue. It narrows
the value list; Select All then reads "(Select All Search Results)" and
covers only the matches, and Apply keeps only the checked matches. The box
takes focus when the menu opens, so typing no longer lands in the active
cell.

An icon-set rule without stored thresholds (every rule made by
home.conditionalFormat, and the sales sample) was written as an empty
<iconSet>, which CT_IconSet forbids (cfvo minOccurs 2); openpyxl drops it.
The writer now always emits one cfvo per icon: the stored thresholds when
there is one per icon, the lower bound prepended when it is missing, else
Excel's defaults (percent 0/33/67, 0/25/50/75, 0/20/40/60/80).
Evaluation read the thresholds as one fewer than the icons, but files
carry one per icon (the first is the lower bound), so thresholds read from
a file were ignored. Both now share icon_count and default_icon_thresholds
in gridcraft-model; icon_count is clamped to 3..=5 so a set name like
"0Foo" can't underflow k - 1.
