Conflict: crates/compose/src/tests.rs: next's plus d0120bf6's optical_kerning_leaves_dash_pairs_alone
Two dashes end to end have no ink gap to measure, so -- and the double
em dash opened up by the loosen cap; Chinese sets —— as one continuous
rule. Fullwidth Latin (U+FF21–FF5A) was kernable through its Latin
script and moved CJK text off its em grid. Both are now excluded from
kernable(), with a unit test and a compose test that failed before.
Optical kerning was treated exactly like Metrics: the font's kern pairs
and nothing else, so text set with Optical in InDesign came out wider,
rewrapped and went overset in tightly fitted frames.
Now the font's pairs are turned off for Optical text and each pair is
spaced from its outlines (crates/compose/src/optical.rs): every glyph's
ink is sampled into 28 bands across the em, the pair's mean and smallest
ink gap over the bands both glyphs ink are compared with the font's
stem-to-stem gap (the pair nn, or HH then oo), and the pair moves 60% of
the way towards it, keeping 30% of that gap and moving at most -0.12 or
+0.06 em. Latin, Greek and Cyrillic letters, digits and Western
punctuation take part; spaces, marks, missing glyphs, right-to-left
runs, upright and tate-chu-yoko glyphs and pairs across a fallback font
keep their font spacing. Profiles and references are cached, bounded.
Tests: AV, To and r. close up and nn stays; HH closes up under Optical
but not Metrics (fails on main); every change on a pangram stays within
the bounds and spaces keep their width; profile, gap, adjustment and
character-class unit tests.

Conflicts:
- Cargo.lock: designcraft-compose depends on both unicode-script (#427)
and unicode-segmentation (next).
- ROADMAP.md: the optical kerning progress-log line goes above next's two
2026-10-11 lines. Status line keeps next's Last reviewed date and names
both changes.
- docs/gaps.md, docs/typography-parity.md: same status-line merge.
The system font scan also reads the font files CoreText has available
(core-text's collection of all available fonts, safe API), so fonts that
Adobe Fonts, RightFont and other font managers register from their own
folders are cataloged. Files the font folders already hold are read once;
paths that lead to no file are skipped. FontDb::global serves the desktop
app and designcraft-cli alike; the scan stays in the background.
Fixes#261, #327.

Lines beside an object that lets text through on both sides are set in
segments, left then right, and the paragraph runs on from one to the
next. One-sided wraps (left, right, spine sides, largest area) block the
other side. A contour wrap follows the object's outline band by band,
with the offset around it; graphic frames follow their contour type
(bounding box of the graphic, frame path, same as clipping; detected
edges, alpha channel and image paths follow the frame path). The Text
Wrap panel sets the wrap side and contour type through object.textWrap,
and IDML import and export keep ContourOption.
Progress docs per craftrules standards/progress-docs.md: target-app parity, gaps, roadmap with alpha gate, readiness by audience (full / mainstream / essentials) with Opus 5.5 hours, and feature, format, hardware, UI and localization parity docs.
