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.

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.

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.

A chart linked to a PivotTable: series are built from the report
(innermost row items x column items/value fields, totals excluded) and
rebuilt on every refresh or layout change; c:pivotSource round trip;
chart series accept union references.

Histogram, box & whisker, waterfall, funnel, treemap and sunburst charts
were written as clustered columns, and reading skipped such charts in
files made by Excel, which keeps them as cx:chartSpace (chartex) parts.
The writer now writes these kinds as chartEx parts, as Excel lays them
out: the data goes through hidden _xlchart.v1.N workbook names, each
part comes with chart style and colour parts, and the drawing frames it
in mc:AlternateContent with a text-box fallback. Fills are written out
(series in theme accents, waterfall decreases and treemap/sunburst boxes
in their own, a white chart area), so they don't depend on the style
part. The reader reads the parts back (resolving the _xlchart names,
which aren't kept as names) with data, title, axis titles, legend,
labels and colours, and follows mc:AlternateContent in drawings.
A Ctrl+Shift+Enter array formula was evaluated like a dynamic array:
- Read from a file, the cached values in its range were kept as
constants, so the formula showed #SPILL! (any multi-cell array
formula saved by Excel or LibreOffice).
- Entered over C2:C4 with a two-value result, C4 stayed blank where
Excel shows #N/A, and a single-cell array formula spilled.
- On save, the values of its other cells were not cached.
The result is now fitted to the range: a single row or column repeats
across it, cells past the result show #N/A, and a larger result is cut
off. Reading drops the cached values inside the range, entering clears
the range, and saving caches its values. The formula bar shows the
formula in braces, {=B2:B3*2}.
Excel anchors a floating object to the grid in one of three ways, stored in the
file as the drawing anchor's `editAs`: "move and size with cells" (twoCellAnchor,
the default), "move but don't size with cells" (oneCellAnchor / editAs="oneCell")
and "don't move or size with cells" (editAs="absolute"). GridCraft had no such
concept: xlsx import dropped `editAs`, export always wrote a plain twoCellAnchor,
and sorting/filtering never moved an object — so pictures stayed put when their
rows were reordered.
Model: add `AnchorMode` on `Anchor` (serde default = MoveAndSize, so existing
documents round-trip unchanged).
xlsx: read the anchor kind and `editAs` into the mode; write it back out
(editAs="oneCell"/"absolute" as Excel does).
Engine: sorting now moves objects anchored inside the sorted body with their
lines, re-fitting "move and size" objects, keeping "move but don't size"
objects' size, and leaving absolute ones pinned. Structural insert/delete
honours the same rule (previously it moved every object's cell unconditionally
and ignored shapes). New `object.setAnchorMode` command sets an object's mode;
`arrange.selectionPane` reports it.
Tests: sort moves images with their rows; absolute objects stay put across a
sort and a row delete; move-only keeps its size; the mode survives an xlsx
round-trip; the drawing fixture parses all three anchor kinds.
