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.
Port the CJK1 and AR1 changes from 3ecdb78 and de83cdc onto current main. Resolve translation and font-stack conflicts by retaining main localization and craft-fonts integration while preserving all typesetting code, tests, and documentation.
Validation: all six CI gates passed, including 616 tests and WASM checks.
An .xlsx cell reference far from the others no longer allocates the whole
range before the cell cap (billions of cells, out of memory), and long
column names can't overflow. IDML import doesn't trust zip part sizes for
up-front allocation and adds header/footer counts saturating. Tagged Text
and IDML export use let-else; the font fallback has a compiled-in last
resort. These crates deny the panicking lints.

- color: Swatch.hidden — unnamed colours (applied, not listed in Swatches until added)
- engine: object.color (reuses a swatch with the same colour, else an unnamed one; fill or
stroke), swatch.addToSwatches (optionally named; users follow the rename),
swatch.addUnnamed (+ test)
- UI: Color panel with fill/stroke proxy, CMYK/RGB/Lab, channel sliders with gradient tracks and
value fields, tint slider for named swatches, spectrum ramp, Add to Swatches; Color Picker
dialog (double-click a proxy chip); Swatches hides unnamed colours

- 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)

- doc: OBJECT_MARK with Story::objects (items normalized to the origin) kept in sync on edits,
copy/paste slices and threading
- compose: inline objects are wide glyphs sitting on the baseline (Y offset; auto leading grows);
above-line objects push their line down; placements per frame follow vertical justification
- render + PDF draw anchored items with their lines
- engine: anchored.insert/options/release/list; pasting copied items into text anchors them;
Options/Release act on the object at the insertion point (+ test)
- Object › Anchored Object menu

- doc: INDEX_MARK with Story::index_refs kept in sync (topics 1–4 levels, sort keys, current
page / to end of story / next n paragraphs / suppressed / See / See also); index builder with
section headings, nested or run-in entries, merged page ranges; Document::index for updates
- engine: index.addReference (topic from the selection), index.list, index.generate, index.update
with Index Title / Section Head / Level 1–4 styles (+ tests)
- IDML: PageReference markers and the Index topic tree with See / See also cross-references,
both ways (verified in InDesign 2026)
- Layout › Index menu

- doc: ANCHOR_MARK / XREF_MARK with Story::anchors / xrefs kept in sync on edits, 11 formats
(InDesign's building blocks + partial paragraph), paragraph anchors, typographic quotes
- compose: anchor pages via an XrefIndex (cached per document signature); cross-references are
resolved at composition, so they never go stale; '??' for missing destinations
- PDF: cross-references become link annotations to the destination page
- IDML: export/import as HyperlinkTextDestination / CrossReferenceSource / Hyperlink /
CrossReferenceFormat (+ XRef page variables); verified live in InDesign 2026
- engine: xref.insert/list/setFormat/defineFormat/formats, anchor.create/list (+ tests)
- UI: New Cross-Reference dialog (styles → paragraphs, format); menu pass adding TOC, sections,
text variables, hyperlinks, footnotes, step and repeat, spelling, fitting/content submenus,
effects, Data Merge, Preflight, EPUB; fixed-parameter menu variants; ui.menu.invoke opens
generated dialogs; every-menu-entry-is-a-command test
