Brandon ThomasandClaude Opus 5.5 7cb62d5197 Pptx/Render: picture fills with rotWithShape=0 stay upright
A shape's picture fill marked not to rotate with the shape turned and
flipped with it (rotWithShape was neither kept nor written: always 1).
PowerPoint keeps such a picture upright, stretched (or tiled) over the
box the rotated shape covers on the slide and clipped to the shape. Now
read, written (PictureFill::upright) and drawn so.

Wild synthetic set: picture fills on rotated/flipped shapes 12.89 ->
3.87.

Brandon ThomasandClaude Opus 5.5 675d20417e Pictures: black and white, inverted alpha, and PowerPoint's grey weights
- a:biLevel (Color > Black and White) was ignored. It is now read, written
  and drawn: white where the luminance reaches the threshold, else black
  (observed thresholds at 30/50/70% on colour swatches).
- a:alphaInv was ignored; an opaque picture with it is invisible in
  PowerPoint. Now read, written and drawn.
- Grayscale, duotone and saturation weighed channels 0.299/0.587/0.114;
  PowerPoint's export greys pure red to 54 and green to 182: Rec. 709
  weights (0.2126/0.7152/0.0722).

Wild synthetic set: recolour slide 7.60 -> 1.15, picture corrections
13.36 -> 7.36.

Brandon ThomasandClaude Opus 5.5 0c5ddb5dea Gradients: read, write and draw a:tileRect
Gradient tile rectangles were dropped on import. PowerPoint's "from
corner" radial presets depend on them: fillToRect puts the focus on a
corner and tileRect stretches the gradient's box a whole size past it, so
the circle is centred on that corner and reaches the far one. Without it
(after the two-point radial change) such fills washed out. A linear
gradient now spans its tile rectangle; a radial one ends on the circle
around it, with the focus still placed in the shape's own box (fitted to
PowerPoint's export of the corpus deck tdf114848: mean diff over the
filled box 0.77). Round-trips through pptx.

Wild synthetic set: tile-rect gradients 16.74 -> 2.48.

Brandon ThomasandClaude Opus 5.5 9d571ef644 Selection Pane: reorder by drag and drop, groups, Show/Hide All and Lock, as in PowerPoint (#133) (#332)
* #133: Selection pane engine: restack inside groups, Show/Hide All, Lock like PowerPoint

- arrange.bringForward/sendBackward/bringToFront/sendToBack and arrange.reorder work on a
  group's children, which stay in their group (as PowerPoint's pane arrows and drag do);
  steps that change nothing leave no undo step.
- selection.select (pane click: Ctrl toggles, children and top-level objects don't mix,
  picking a hidden object shows it), selection.showAll (everything, children too) and
  selection.hideAll (top level).
- shape.lock cascades through groups; locked objects can be selected, formatted and typed
  in, but not moved, sized, rotated, flipped, reshaped or cropped (commands and canvas).
- PPTX: Lock reads and writes PowerPoint's full locking attribute set per element kind
  (observed by saving locked objects from PowerPoint); partial locks aren't Lock.

* Front-most first with groups folding; drag a row to restack among its siblings (accent
insertion line); Bring Forward / Send Backward arrows; Show All / Hide All; per-row eye and
padlock; double-click or F2 renames in place; Ctrl+click toggles, Shift+click selects a run;
arrows, Home, End and Esc in the list; right-click menu. Lock/Unlock on the canvas menu,
greyed handles on locked objects. egui_kittest tests drive the pane.

Brandon ThomasandClaude Opus 5.5 dedb20890b Text: WordArt transforms (prstTxWarp) draw, and their adjusts round-trip (#312)
* Text warps: draw WordArt prstTxWarp presets, round-trip their adjusts

All 40 DrawingML text-warp presets now render instead of drawing flat text.
A warp is a list of bands over the shape's text rectangle (insets ignored):
fill bands stretch the ink of their lines between a top and a bottom guide
(positions by arc length, one horizontal scale for the whole text), follow
bands (arch, circle, button) set lines at natural size along an ellipse arc,
lines stacking outwards on parallel curves, with no wrapping. Lines are
shared over multi-band presets in order (ceil(n/k) per band).

The guide curves were fitted to PowerPoint renders of synthetic decks of
"I" bars (black-box observation, defaults and changed adjusts, 1-3 lines);
most presets match within about a point on a 420 x 200 pt box.

- geom: warp module (guides, presets, band mapping) with unit tests
- render: glyph outlines and underlines flattened, subdivided and mapped
- text: follow warps lay out without wrapping
- model/pptx: BodyProps.warp_adj read from and written to prstTxWarp/avLst

* Text warps: bands with fewer lines keep the fuller band's text height

Multi-band fill warps (Deflate-Inflate, Button Pour) map a box as tall as
the tallest band's ink onto every band, centred on the band's own ink, as
PowerPoint does: a band holding one line next to a band of two keeps the
line at the same size instead of stretching it over the whole band.

Brandon ThomasandClaude Opus 5.5 d8407c11f9 Tables: styles the file defines are read, drawn and kept (#292)
* Tables: styles the file defines are read, drawn and kept

PowerPoint writes the definition of every table style a deck uses into
ppt/tableStyles.xml. DeckCraft mapped a handful of GUIDs to its own looks
and drew any other style as Medium Style 2, so themed and light styles came
out in the wrong colours, and dropped the definitions on save.

The reader now keeps each definition (whole table, bands, first/last
rows and columns, corner cells, table background; fills, theme fill and
line references, borders, text colour and bold) on the presentation, and
tables using one keep its GUID. The renderer applies the parts that cover
each cell in the spec's order, a part's edge lines on its region's edges
and its inside lines within it, and paints fills as real fills (gradients
and see-through colours). The writer puts the definitions back as read.

Brandon ThomasandClaude Opus 5.5 8b160d5b03 Text: wrap URLs, Korean and CJK punctuation where PowerPoint does (#276)
* Text: wrap lines where PowerPoint does

- Without latinLnBrk (PowerPoint's default) a word doesn't break after '/'
  or '\': URLs and paths fill the line and break at its edge.
- Korean wraps between words, not between syllables.
- With hangingPunct, closing East Asian punctuation hangs past the end of
  the line instead of dragging the previous character down.

ParaProps gains latin_line_break and hanging_punct, read and written as
latinLnBrk and hangingPunct.

Brandon ThomasandClaude Opus 5.5 4d13652f0f Pictures: duotone recolours, and layout/slide colour map overrides apply (#269)
Theme background pictures (Office 2007-era themes such as Treck) carry an
a:duotone recolour in phClr; DeckCraft read it but drew the picture
unchanged, so those backgrounds came out grey. The painter now resolves the
duotone's colours against the slide's colours and placeholder colour, and
the decoded-image cache applies them (luminance picks a colour between dark
and light) and keys on them.

Layouts and slides can replace the master's colour map
(p:clrMapOvr/a:overrideClrMapping, e.g. dark section layouts mapping bg1 to
dk1). They were read as the master's map; now Layout and Slide carry an
optional colour map, resolve::Ctx uses slide > layout > master, and the
writer keeps them.

4b09f35c1d feat(text, fonts): UAX #9 BiDi and Arabic complex script typography engine (#4)
* Sprint 1: bidi and Arabic typography engine

fonts: ISO 15924 script and a:latin/a:ea/a:cs slot classification;
shape_range shapes an item with the whole paragraph as HarfRust
pre/post context, explicit script/language/direction, glyphs kept in
visual order; per-grapheme-cluster fallback (slot face, theme script
font, OS cascade families, bundled craft-fonts face); GDEF ligature
carets.

text: UAX #9 levels for the whole paragraph (a:pPr/@rtl), itemization
by level, script, face and shaping style (paint-only changes no longer
split words), logical line breaking at cluster boundaries, per-line
L1/L2 reordering (L4 mirroring by the shaper); RTL start edge and
bullets, justLow kashida; caret Affinity, logical/visual movement,
bidi hit testing and selection as the union of visual boxes.

model/pptx: theme a:font script fonts and algn="justLow" round-trip.
engine: format.rtl (Right-to-Left Text Direction), justifyLow align.

* Fonts: the bundled script face comes before installed fonts; no Microsoft family names

Arabic, Hebrew, Thai and Devanagari clusters try the craft-fonts face first, so every machine
draws the same, then openly licensed or OS-native installed families, then any installed face.
Installed Microsoft faces are still used through that scan, but not named (AGENTS.md §1.1).
