* Colors: unknown preset and system colour names are rejected, and the writer saves black or windowText for them
* Gaps: copying text and cell ranges, list AutoFormat's option and Backspace, and a timing-sensitive control-server test
* Paste and Compare: media kept under a foreign id raises the next id, so a later picture gets an id of its own
* Tables: with a cell range selected, a press on the table outside its cells selects and moves the table
* Tables: a click on a selected table's grab band keeps the table selected instead of entering the nearest cell
PowerPoint draws a picture's own fill (p:pic/p:spPr) behind the picture, so
it shows through its transparent pixels: a synthetic deck with one
half-transparent PNG three times (no fill, an orange fill, a yellow fill
with a blue outline), exported as PDF, shows the orange and yellow boxes
behind the image. DeckCraft drew the outline but never the fill.
Old equation objects use this: an OLE object (p:oleObj, Equation.3) has a
fallback picture whose spPr gives it a coloured box behind the equation's
transparent metafile. The reader took only the picture's image as the
object's preview and dropped its fill and line.
- The shape-fill loop moves into Renderer::fill_geometry; a picture and an
embedded object's preview paint their own explicit fill with it before
the image (a style fill alone still draws nothing, as before).
- An embedded object without a fill or line of its own takes them from
its fallback picture's spPr; its frame keeps its own position.

* fix(pptx): harden import resource budgets, deduplication, and lookup caching
- Chart sidecars (Finding 2): Enforce an import-wide retained byte budget
and cache captured sidecars by chart part to prevent memory amplification.
- Content types cache (Finding 6): Cache parsed [Content_Types].xml defaults
and overrides in Package.ct_cache.
- Text run splitting and font lengths (Finding 8): Bound typeface attribute
lengths and cap paragraph runs to prevent multiplication on text splitting.
- Inner namespace decls (Finding 15): Use HashSet/HashMap indexing and cap
inner declarations to 1,000.
- Slide and notes deduplication (Finding 16): Deduplicate slide paths and
cache parsed notes slide bodies by target.
- Diagram media caching (Finding 22): Cache diagram media payloads in
imp.media_by_part.
- Master slide deduplication (Finding 28): Deduplicate master paths before
loading.
- Layout target deduplication (Finding 30): Deduplicate layout targets
across master slides.
- Chart value axis indexing (Finding 32): Index valAx by axId using a HashMap.
- ChartEx series output budget (Finding 34): Charge series point vectors
against an aggregate output budget and cap series count.
- ChartEx point allocation bounds (Finding 36): Allocate point vectors
only to actual point span bounded by budget rather than declared ptCount.
- SmartArt recursion depth (Finding 38): Limit SmartArt recursion depth to 8.
* fix(pptx): address review feedback on sidecar cache, series budget, and inner decls
* fix(pptx): preserve cached sidecar bytes and non-empty category fallback

ROADMAP.md: union of log rows. docs/animation-parity.md: main's header; the by-paragraph row from the PR, the triggers row from main; both revision rows.
`Chart::text_color` was read from a .pptx (the axes', legend's or chart's
`c:txPr`) but never written, and any edit drops the kept part and rebuilds
it from the model, so a save after an edit lost the colour. The writer now
puts it where PowerPoint keeps it: `c:txPr` on both axes, the legend, the
data labels and the chart root, and the run defaults of the title's rich
text (chart and axis titles). Nothing is written without a colour, so the
theme default still applies on reading.
Round-trip tests: a scheme colour with a lumMod, an RGB colour and no
colour come back as set; a chart read with a `tx1` 65 %/35 % colour on its
axis keeps it through a title edit and a rebuild of the part.

A bar series' own fill was read only when solid or a gradient: a pattern
(a:pattFill) was dropped, and an a:noFill series was read but drawn in the
palette's colour anyway, because the chart renderer turned every fill into
one colour and fell back to the palette for anything but solid. PowerPoint
for Mac draws the pattern, leaves an a:noFill bar empty and draws its
outline (c:spPr/a:ln) where it has one: a synthetic column chart with a
red-on-yellow dkDnDiag series, an empty series with a 3 pt blue outline
and an empty one without, exported as PDF, shows exactly that, legend
keys included.
- The chart reader reads a:pattFill (dml::pattern, shared with shapes);
the chart writer writes it back for an edited chart.
- Bars and their legend keys paint with the series' or point's own fill:
a colour, a preset pattern (pattern::fill) or nothing, then the series'
solid outline at its width.
- Lines, areas and markers, which take one colour, use a pattern's
foreground colour instead of the palette's.

A shape whose text has no anchor of its own (`<a:bodyPr/>`) was given the
anchor of the theme's shape defaults (`a:objectDefaults/a:spDef/a:bodyPr`),
which Office's themes set to `ctr`, so its text was centred in the box.
PowerPoint for Mac draws such text at the top: a synthetic deck with an
spDef anchor="ctr" and three rectangles (`<a:bodyPr/>`, anchor="t",
anchor="ctr"), exported as PDF, puts the first two at the top. The spDef
defaults are for shapes inserted later.
Opening a file now anchors every shape without an anchor at the top, as
the standard has it; the model's middle default is still written as ctr.

The reader stored a series-level `c:dLbls/c:showVal` in
`Series.data_labels`, but every drawing path tested only the chart-wide
`Chart.data_labels`: a series that asked for labels got none, and a
series that asked for none got them. The series' own setting now wins,
and a bare `<c:showVal/>` (no `val` attribute) means true, as the
schema's default.
The plot group's own setting is respected too: a group that asks for no
labels keeps them off, even when another group of a combo chart asks for
them. Before, any group that asked turned the chart-wide setting on, and
the group that said no inherited it.
Tests: `crates/pptx/tests/chart_data_labels.rs` - a bare series
`showVal` shows that series' labels while its siblings stay quiet; an
explicit `val="0"` on the first series keeps it quiet under a chart-wide
on; a combo chart keeps each group's own setting; all three settings
round-trip. Red-proof: with the series-level setting ignored, the first
two fail; with the group's setting ignored, the combo chart's bar group
shows labels it asked to keep quiet.
The model gains `Chart::series_data_labels`, the one place that decides
whether a series' labels show; the render paths (bar, column, line,
area, pie, doughnut, radar, scatter) call it.

p188:cmLst declared only xmlns:p188 but its comment bodies use a:bodyPr, a:p, a:r and
a:t, so the part was not namespace-well-formed and PowerPoint refused the saved file.
A regression test parses every written XML part with a namespace-aware reader.

The importer skipped a slide whose part was missing or unreadable and only
logged it, so `info` showed one slide fewer with exit code 0 and a save wrote
the shorter deck over the original.
`deckcraft_pptx::import_checked` returns the parts it left out (`import` is
unchanged). The engine carries them as `Damage::slides` next to the damaged
media of a `.deckcraft` file: `file.open` and `file.openBytes` return
`lostSlides`, the app shows a message and opens a repaired copy (so Save asks
for a new name), and `deckcraft-cli` warns on stderr.

Conflicts resolved onto main's newer shape, and the PR's policy applied to
every alloc_id/add_media/new_slide call site main has grown since: commands
answer bad(cmd, NO_ID_SPACE) (slide.reuse, insert.zoom, SmartArt, photo
album, review.accept, handout/notes masters, master placeholders,
background/artistic/compress pictures, transition sound, ink to shape,
paste special, file.new templates); reid/bring_media/renumber/regenerate
and compare::adopt/accept are fallible; outline import keeps what fit.
Tests use expect() on the now-Option results.

Fix-ups in the merge (review): zoom targets, sections and titles are looked up with get()
instead of indexing; Hyperlink literals carry both main's sound fields and zoom_return;
duplicated test statements left by the test-file union are removed.

Shape3d::parse scanned the kept a:scene3d/a:sp3d XML as strings and copied the
camera, light rig, direction, material and bevel names from the file into the
XML it writes back unescaped. It now parses the fragment with the importer's
XML reader (exported from deckcraft-pptx as parse_xml) and keeps a value only
when it is in the format's lists (ST_PresetCameraType, ST_LightRigType,
ST_LightRigDirection, ST_PresetMaterialType, ST_BevelPresetType), else the
default; lengths are clamped and the extrusion/contour colours are
re-serialized (escaped) by the XML writer. The Format Shape pane rows in
ui-parity.md that earlier merges had duplicated are folded into one.

A chart's kept parts were written under the names the source file gave them,
so a relationship to ppt/media/image1.png (or any name the writer generates)
produced a second zip entry with that name on save. Kept parts are now written
as ppt/<folder>/keptN.<ext> with a content-type override each, the chart's and
the kept parts' own relationships are rewritten to the new names (relationships
to parts that were not kept are dropped), and the package writer skips any
second entry under a name it already wrote. externalData/userShapes are dropped
only when their relationship is not written back.
Office 2016 chartex charts (added on main since the PR) capture and write back
their kept parts the same way; the plain-chart fallback carries none.

Fix-ups in the merge (review): uniform-width and highlighter strokes are drawn as one path (on
the slide and in the live preview) so see-through ink doesn't darken where segments overlap;
segment pairs are destructured instead of indexed; tests that build pointer events set the new
pressure field.

Fix-ups in the merge: error-bar statistics are computed once per series (was once per point,
quadratic on long series); reading custom amounts uses the chart-wide point budget (#480).

- #178: ToUnicode ranges looked up without indexing
- #465: frame_num gaps are concealed (bounded) even when the SPS forbids them; cut streams keep playing
- #471: control request lines up to 256 MB so picture/media inserts still fit
- #473: a merge that loses its only row or column is removed, with regression tests
- #521: AutoCorrect no longer rewrites real words (cant, wont, im)
- #654: inherit_placeholder_geometry's doc comment back on its function
