Every datetime field showed the deck-wide fixed date text instead of a date: empty when no slide
had a fixed date, and that text on every slide when one did. A fixed date is plain text in its
slide's placeholder; a field is an automatic date, so it now shows the local date and time in the
format of its type (ECMA-376 datetime1 to datetime13 as PowerPoint lists them for English,
datetime and datetimeFigureOut the short date). Numeric dates follow the run's language
(en-GB 09/10/2026, de-DE 09.10.2026...); formats with names stay English-only, so other languages
keep the field's saved text, as do unknown types and builds without a clock (wasm). The saved
text is kept on save.
- text: datetime module (field types, formats, local clock via chrono, not on wasm);
Fields::field_in passes the run's language.
- render: RenderOpts::now injects the clock (tests, deterministic output); the PDF text layer
uses the same fields.
- engine: Header & Footer turns existing date placeholders into fixed text or back into a
field; new date fields are saved with the date they show (local, not UTC).

* 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).
