text_width sums in u64; an all-zero or non-finite dash array is written as
solid ([] 0 d); stroke widths are clamped to >= 0 (NaN -> 0); drawing calls
with non-finite or non-positive geometry return before storing anything.

Info strings were WinAnsi; PDF text strings are PDFDocEncoding or UTF-16BE.
Printable ASCII stays a literal string; anything else is a <FEFF...> hex
string. Info strings are capped at 1024 characters.

home.rowHeight, home.autofitRowHeight and data.ungroup change row hidden
state without marking the edit structural, so SUBTOTAL(101-111) kept a stale
value. Found by the command-sequence fuzz (seed 3).

home.deleteRows/deleteColumns used only the last selected area. They now
take every area (or a comma list like "3:3,7:8"), merge them and delete
from the last to the first inside one edit, so it is one undo step.

XLSX headerFooter kept only oddHeader/oddFooter: a workbook whose header is on a
different first page (differentFirst + firstHeader) or on even pages showed no
header, and saving dropped it. The model now keeps the first/even headers and
footers and the differentFirst / differentOddEven / scaleWithDoc / alignWithMargins
flags; XLSX reads and writes them; the PDF and the Page Layout view use the right
pair per page; in-place editing edits the page's own pair, and the Header & Footer
tab has Different First Page and Different Odd & Even Pages. pageLayout.headerFooter
takes the variants and a page: odd|even|first for one-section edits.
Insert › Header & Footer now switches to Page Layout view and edits the first
page's centre header, as in Excel, instead of opening the codes dialog.

On macOS the UI font (SF) has no Hebrew and no Hebrew fallback face was
found, while cells in Arial drew it: the formula bar showed boxes. The
interface families now carry the cell face ahead of the script fallbacks,
and the macOS Hebrew candidates include ArialHB.ttc / SFHebrew.ttf /
LucidaGrande.ttc.

Text boxes ignored a:rPr (size, bold, italic, typeface, fill, outline),
a:pPr algn, a:bodyPr anchor and spPr/a:ln/a:noFill. They are now read into
Shape::format, drawn on screen and in PDF, and written back.

Since #209, printing from the UI hands the print PDF to Services::print, which only
the web build set: on the desktop, Ctrl+P, More › Print, the macOS menu and the
Backstage Print button produced the PDF and dropped it. The desktop app now writes
it to the temporary folder and opens it in the system PDF viewer, whose Print
reaches the printer dialog.
Save As has a Save as type chooser (xlsx, csv, html, pdf); file.save and
file.saveAs with a .pdf path write a PDF of the sheet (they wrote XLSX bytes into
the .pdf and made it the workbook's file). The desktop save picker honours the
suggested type instead of always proposing .xlsx. The macOS Properties item opens
File › Info instead of running file.properties with no fields.

Sheet protection stored an internal FNV hash that was never written to
XLSX, and an Excel sheet password was dropped on import, so imported
protected sheets could be unprotected without it. Protect Sheet now
stores a salted SHA-512 hash (spin count 100000) via PasswordHash; the
XLSX sheetProtection password (iterated or legacy) is read and written,
and Unprotect Sheet really verifies it. Hashes from older GridCraft JSON
workbooks are still read and verified.
