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

Re-protecting a password-protected sheet would drop its hash and let a
plain Unprotect succeed; it is now refused. The sheet tab menu offers
Unprotect Sheet on a protected sheet, like the ribbon.

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.

Grouped rows and columns now get Excel's outline band beside the headers:
a bracket per group, a -/+ button on the summary line and level buttons
in the corner. The buttons run data.hideDetail / data.showDetail and the
new data.showLevels, so they undo. Hide Detail marks the summary line
collapsed, Show Detail keeps inner groups that were collapsed on their
own, and Group / Ungroup take by: rows|cols. Show Detail and Hide Detail
are on the Data tab and in the Data menu, the group shortcuts are listed
as Alt+Shift+Right / Left, and shortcut lookup reads navigation keys by
their logical key so the numpad arrows work.

The ribbon button toggled structure protection silently. It now opens a
Protect Structure and Windows dialog with an optional password; when a
password was set, unprotecting asks for it and really verifies it
(SHA-512, spin count 100000, salted). The password hash is read from and
written to XLSX workbookProtection (workbookAlgorithmName/HashValue/
SaltValue/SpinCount or the legacy workbookPassword); an unreadable one
stays locked. File › Info uses the same flow.

The model read topLeftCell but the grid always opened at A1 and never wrote
the current scroll back. Sheets now open scrolled to their saved first
visible cell; saves record the current one (and the active cell) without
dirtying the workbook. Frozen panes use the pane's topLeftCell.
