* 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.

PowerPoint leaves an inheriting placeholder's spPr without a geometry and
draws it with its layout (or master) placeholder's: a picture placeholder
cut into a shape, or with holes, keeps that shape on every slide. DeckCraft
read such placeholders as rectangles. They're now marked while reading
and given their parent's geometry once the layouts are read; anything
without a parent stays a rectangle. DeckCraft itself already writes
inheriting placeholders this way.

A shape or background blipFill with neither a:stretch nor a:tile (as some
tools write it, tdf#128596) was stretched across the shape; PowerPoint
tiles the picture at its own size.

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.

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).

`sniff` searched only the leading 4096 bytes for the content-types part, but
OOXML writers may place that part anywhere in the archive. Recent PowerPoint
builds (16.x) store it as the last zip entry, so every deck saved by them was
rejected with "not a presentation DeckCraft can read" although it imports fine.
In one real folder 169 of 300 decks were affected.
Look the part up in the zip's central directory instead. The regression test
re-packs the sample deck with the part last behind 64 KB of padding and
checks that it is both recognised and imported.
