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.

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).
