text_line flipped glyph outlines that the font database already gives
y-down, so each family's preview in the font menu was drawn upside down
below its baseline and cut off at the bottom of the image.
Font menus list Western (and other-script) families first, then
Japanese, Simplified Chinese, Traditional Chinese and Korean families,
each group alphabetical by the name shown, with a separator between
groups. The group comes from the font's own data, strongest signal
first: the meta table's dlng (else slng) languages, family names in a
CJK language (Windows and Macintosh language IDs), OS/2 code pages (JIS,
Chinese Simplified, Korean Wansung, Chinese Traditional, Korean Johab);
a font declaring none of these goes by what it covers (kana, Hangul,
ideographs). Ties go Japanese, Simplified, Traditional, Korean. Loaded faces are classified
once; installed fonts by the font scan, which also reads their OS/2 and
meta tables (and cmap only for fonts declaring nothing), capped.
CJK families show their family name in their language, the English
name on hover; Preferences > Type > Show Font Names in English
(prefs.set {showFontNamesInEnglish}, off by default) shows English
names. Search matches either name; documents store the English name.
The Character panel, Control bar, Properties, style dialogs, Find Font
and Glyphs panel lists all follow this order. The main font menu stays
open while searching or starring (it closed on any click inside).
Font previews don't draw DesignCraft's missing-glyph box for fonts
whose .notdef is empty.
The fonts in a document's Document Fonts folder are registered under a
font scope that the document holds while it is open (Document::font_scope,
runtime only; DocState keeps the scope alive and closes it when the last
copy of the state goes: file.close, closing a tab, revert, a book
chapter's export, the session ending). Composition, preflight, font.list,
Package and the font menus, Glyphs panel and previews look fonts up
through FontDb::scoped(scope): the document's own faces first, then the
shared ones. Other open documents don't see them, and two documents with
fonts of the same name each set text in their own. Composite fonts'
member fonts and the fallback for kenten marks are looked up the same
way.
Font files stay in memory for the session (FaceRef keeps faces for the
process); a document opened again reuses the faces of its unchanged files
(same path, length and modification time) instead of reading them again.
The composition cache's signature includes the scope; the word cache and
the outline and PDF font caches are keyed by face. Variable font
instances are kept per base face.
A family's installed faces join the shared fonts all at once, and a
face two lookups load at the same time is kept once, so a parallel
fallback lookup never takes a family's bold before its regular has
loaded.
Vertical is a story property: every frame of a thread is vertical or
horizontal together, a frame threaded onto a story takes its direction,
and frames split off by threading or breaking a thread keep theirs.
Type > Story Direction is type.storyDirection {vertical} (checked in the
menu) for the stories of the text selection or selected frames;
object.textFrameOptions {vertical} and frame.create {vertical} set the
frames' stories. Documents that stored Vertical on the frame open with
each story taking its first frame's direction. IDML StoryOrientation is
read into and written from the story, beside its column direction
(StoryDirection), which stays a separate setting.
Rasters stay below vello_cpu's u16 limits (a 65535-pixel-wide render
panicked inside it), page renders larger than 2^29 pixels decline instead of
allocating, PNG encoding never panics, and the PDF heading tag can't fail.
Both crates deny the panicking lints.

- Edit › Paste Into (⌥⌘V): copied objects (with their stories and images) become the selected
frame's content, clipped by it; Item::is_group / has_nested_items; renderer and PDF draw fill,
clipped content, stroke; IDML nests the items inside the frame both ways (verified in
InDesign 2026) (+ tests)
- Polygon Settings: sides and star inset as engine preferences used by the polygon tools and
frame.create; double-click the Polygon tool (+ test)

- render: damage()/damage_with() — changed items and only the frames whose composition changed
(cache keeps the composition each edit replaced; Cache::composed_for matches a document
version exactly); conservative full repaint for styles, swatches, layers, parents, wrap,
effects and cross-story text (+ tests incl. pixel-identical patch vs full render)
- UI: canvas patches its texture after edits with the view unchanged (0.6 ms vs 22 ms on the
sample when typing); perf harness row for the damage repaint
