A page that frames GridCraft on the same origin can now open workbooks
in it and store what it saves, through postMessage, instead of Save and
Export becoming browser downloads. Built for a Nextcloud integration,
but nothing in it is host-specific.
Only the web shell changes:
- gridcraft:open from the parent goes through the inbox, like a picked
or dropped file
- Services::download sends the bytes to the parent (gridcraft:save); an
.xlsx workbook handed over counts as saved under that name
- gridcraft:dirty reports unsaved changes; gridcraft:ready and
gridcraft:failed report start-up
- in host mode no sample opens, and ?author= names the user for notes
and comments
Enabled only by ?host=parent inside a frame; only the parent window on
the page's own origin is heard or answered. Without it nothing changes.

A save without a recent user gesture (e.g. over the control channel) is refused with SecurityError and would otherwise fail silently.

Clean-room import of Excel 97-2003 workbooks from the public [MS-CFB] and
[MS-XLS] specifications: compound-file streams (FAT, mini FAT, directory
tree), the BIFF8 Workbook stream with Continue records, shared strings,
all cell records, formulas decoded from Ptg tokens (shared and array
formulas, 3-D refs, names, add-in/newer functions by name) with cached
results, number formats, the 1904 date system, merges, column widths, row
heights, defined names and print areas/titles. Encrypted (FILEPASS) and
BIFF5 files are refused with a clear message; everything else is skipped
with a warning. .xls opens as a new unsaved workbook (Save As .xlsx).

The web build had no way to actually print — Ctrl+P (Cmd+P, declared on
file.print's shortcut) did nothing at all, and the ribbon's "Print…" menu
item ran file.print and silently discarded the result. file.print already
builds a PDF and returns it as base64 specifically "for the UI to hand to
the system print dialog" per its own doc comment — this wires that up.
- ui-egui: new Services::print hook (web: hand PDF bytes to the browser's
print flow directly, no download); SheetApp::print_now runs file.print,
decodes the base64 result, and calls the hook.
- ui-egui: Key::P now dispatches to print_now (was unbound); the ribbon's
"Print…" menu item calls print_now instead of discarding file.print's
result.
- gridcraft-web: implements the hook (Blob -> object URL -> hidden iframe
-> iframe.contentWindow.print() on load).
Desktop builds are unaffected (no Services::print set there; print_now
falls back to the existing alert-on-error behaviour with no UI action on
success, same as before this change).

Rebased onto main (conflicts with #83/#98 and main resolved by maintainer); the contributor's branch does not allow maintainer edits.

Merge the fixed#31 branch (which carries #38's font fallback) and resolve:
- theme.rs: build on #38's fallback_faces/load_fallback instead of the old
load_cjk. The interface language only reorders the two Han entries
(sys-cjk-han-ja / sys-cjk-han-zh; Japanese first for ja, Chinese first
otherwise); Hangul, Thai and Hebrew keep their place. The region-merged
Noto Sans CJK .ttc is loaded once, with the leading language's face index.
- Fonts are rebuilt on a language switch only when the Han order changes
(HanOrder), not on every switch. font_definitions()/setup_context() use
the default order and never read the host locale.
- Tests stay locale-independent (UiState defaults to English; the desktop
app applies the system language). The web build follows the browser
language except CJK, which would render as tofu without system fonts.
- app.language.set error/params list all five codes; engine.commands lists
it. zh/ko/ru gain the keys #31 added (Page Layout|Orientation, display
theme). The Page Layout screen checkbox keeps English "View" via a
"Sheet Options|View" key (was shown as "Screen").
- Coverage test checks zh/ja/ko/Thai/Hebrew/Cyrillic in both the UI and
cell families by comparing glyphs with the tofu glyph.

Blank cell and row repeats that run past 16384 columns / 1048576 rows
(padding from writers with larger sheets) are clipped instead of
rejecting the file; any data or merge past the edge is still an error.
convert() builds its Cell with ..Cell::value(value) so new Cell fields
take their defaults.

Resolves the shared integration points for both formats: combined sniff,
file.open spec, file filters, MCP description, docs. open_bytes now lets
sniffed content (ODS or XLSB) win over the extension.
