Conflict: ROADMAP.md: took #83's (main's restructured roadmap); the Threading inventory line goes into docs/target-app-parity.md
Conflict: crates/compose/src/lib.rs: kept this branch's undrawn trailing spaces after warichu; comment covers both the spaces and the drop cap
Conflict: crates/idml/src/tests.rs: took #83's (drop cap style as a Dropcap nested style, table style fills through the cascade); this branch has no changes of its own there
Conflict: ROADMAP.md: took main's restructured roadmap; this branch's inventory changes (Keep Lines Together default, IDML defaults, drop caps, IDML Kashidas) go into docs/target-app-parity.md, where the inventory lives now
Conflict: crates/format/src/lib.rs: load runs the format upgrade, then merges duplicate assets; kept both sets of tests
Share duplicate file data while keeping distinct link paths independent, and leave unused assets out of saved documents.
Validation: all six cargo xtask ci gates passed on the merge candidate; 1,170 native tests passed and all 15 WASM packages checked. Independent regression checks cover updates, relinking, embedding, undo and save/reopen.
Task: #420
A font's em box is its BASE em box; else, for a CJK font (its font
menu group isn't Western: meta or name languages, CJK code pages, else
kana, Hangul or ideograph coverage), the OS/2 typo ascender when the
typo ascender and descender span exactly one em; else 0.5 em + cap
height / 2; else 0.88 em. Latin fonts with a one-em typo box, such as
DejaVu Serif, centre on the cap height.
A font's em box is its BASE em box; else it tops at the OS/2 typo
ascender when the typo ascender and descender span exactly one em; else
it is centred on half the cap height (OS/2 sCapHeight, else the H
glyph's top), 0.5 em + cap / 2 above the baseline; else 0.88 em. The Em
Box Height first baseline, vertical text and declared_em_box all use
this one em box; declared_em_box is None only for the 0.88 em fallback.
The first baseline sits the em box top below the frame's top inset: the
font's BASE em box (idtp, else ideo + 1 em), else 0.88 em, for the
largest size on the first line. IDML FirstBaselineOffset="EmboxHeight"
imports and exports as itself; the footnote options list it and the
frame and footnote option commands take emboxHeight.
IDML has no drop cap style attribute. Import reads the nested style list's leading "through 1 Dropcap" entry as the drop cap style; export writes the drop cap style as that entry. The drop cap style counts as that entry when composing, so nested styles after it start after the drop cap.
The layout-parity files (ROADMAP, compose lib/tests, engine text, fonts fontdb, idml import/tests, canvas) resolve as in the merge of main into feat/layout-parity.
Conflict: ROADMAP.md: as feat/layout-parity's merge
Conflict: crates/compose/src/lib.rs: as feat/layout-parity's merge; this branch's trimmed trailing spaces follow main's warichu::place and come before the drop cap splice
Conflict: crates/compose/src/tests.rs: both sides' tests
Conflict: crates/engine/src/cmd/text.rs: as feat/layout-parity's merge; this branch's TypingFormat/typing_format and main's warichu_cmd
Conflict: crates/fonts/src/fontdb.rs: this branch's styles/traits_of/linked_style over style_traits; style_traits falls back to the family without main's format suffix (exact_style_traits)
Conflict: crates/idml/src/import.rs, crates/idml/src/tests.rs, crates/ui-egui/src/canvas.rs: as feat/layout-parity's merge
Conflict: crates/ui-egui/src/control.rs: main's page_index and automation_contract_tests, then this branch's tests module
Conflict: crates/ui-egui/src/lib.rs: this branch's ClipboardFn and main's Inbox of ImportedFile
Conflict: crates/ui-egui/src/menus.rs: main's Quick Apply tests, then this branch's copy and paste keys test
Conflict: ROADMAP.md: this branch's Text engine, IDML interchange and Right-to-left lines; main's FID2, PDF export and Interface language lines
Conflict: crates/compose/src/lib.rs: list labels as main's number_label/bullet_label/empty-paragraph arms, kept in this branch's list_label form that marks label glyphs; main's layout_line call (ends_para, forced_mid) and warichu::place, then the drop cap splice; rule above uses main's first-line column/end_x span with this branch's rule_color; caret(): drop-cap branch, then main's stacked-row metrics
Conflict: crates/compose/src/tests.rs: both sides' tests
Conflict: crates/engine/src/cmd/text.rs: type.para doc lists the drop cap fields and main's rule fields
Conflict: crates/fonts/src/fontdb.rs: both (plausible/measured_top/typo_ascent and without_format_suffix)
Conflict: crates/idml/src/import.rs: main's table style regions, borders and alternating fill/stroke attrs (this branch's alt_fills helper dropped, unused); underline/strikethrough colour from main with this branch's tint(); frame_options takes the object-style chain's TextFramePreference elements, the frame's column rule colour resolved after it
Conflict: crates/idml/src/tests.rs: main's tests, plus this branch's added tests and helpers
Conflict: crates/ui-egui/src/canvas.rs: main's compose::highlight_quads, then this branch's drop-cap highlight
Consecutive paragraphs with the same Split Columns settings form a split
block: their text fills the sub-columns of the column one after the
other from the block's top, inset by the outside gutter and separated by
the inside gutter, then moves on to the next column. When text follows
the block, its last part is balanced across the sub-columns and the text
continues below the deepest one at the full column width; a block that
ends the story fills its sub-columns in turn. Keep options don't apply
between a block's lines.
IDML: SplitColumnInsideGutter and SplitColumnOutsideGutter import and
export (paragraph attributes split_inside_gutter, split_outside_gutter).

* Lists: numbering formats from IDML (A, B, C; i, ii, iii; 01, 02 …)
A paragraph's numbering format, number expression, bullet character and
text after the bullet import from IDML and export back. Numbered labels
come from the expression ("^#.^t", "Tabel ^#^t") with its
metacharacters expanded, in place of a fixed "n." label. Adds 001 and
0001 number styles, keeps letter and roman labels short for huge
numbers, and counts saturate instead of overflowing.
* Lists: an empty paragraph gets no bullet or number
A list paragraph with no characters before its return draws no label,
and numbering carries on past it: in a story's own list, in named lists
(also across stories) and in cross-reference paragraph numbers.

* Set warichu as smaller lines inside the parent line.
Type › Warichu stacks the selected run after the line is broken, closes up the rest of the line, and round-trips the IDML warichu properties. The line break itself still sees the full-size run.
* Keep clicks, the caret, and Up/Down on each warichu row.
The glyphs were already stacked inside the parent line, but hit testing, the caret, and vertical movement still used that parent line. Break minimums, row widths, spacing, and tab leaders now follow the small lines, and underlines sit on the small baseline.

A break character is stored as the last character of the paragraph it
ends, followed by the usual '\n' separator. The story model, paragraph
ranges, styles, editing and every exporter keep splitting paragraphs on
'\n' only, so the change stays in the places that create, lay out or
write break characters:
- IDML import writes the break and ends the paragraph, so the range that
follows keeps its own paragraph style. NextOddPage and NextEvenPage map
to new odd and even page break characters; IDML export writes a
paragraph that ends in a break as that one Br with its
ParagraphBreakType, so export and re-import give the same story.
- Word and RTF import, Type > Insert Break Character (with odd and even
page breaks added) and typing end the paragraph after a break. Typing
between a break and its return goes to the next paragraph; deleting
either deletes both.
- Layout: a break that ends a paragraph leaves no empty line; the next
paragraph starts in the next column, frame or page, as a paragraph start
option would. Page breaks and Next Page start options move to the next
frame on a later page; odd and even ones to the next page with that
page number parity (no such frame: overset). A break inside a paragraph
from an older document still moves the rest of that paragraph on.
Storing the break as a paragraph separator of its own would have changed
every place that counts or splits paragraphs on '\n'.

* Text frames: column rules draw between columns on screen and in PDF
A frame with Column Rule on gets a bar centred in each gutter, inside the
insets, broken around paragraphs that span columns; right-to-left and
vertical frames included. object.textFrameOptions takes columnRuleWeight
and columnRuleColor (unknown swatches are an error) and an inset array
whose null sides stay; document.inspect reports the rule.
* Text Frame Options: Column Rules fields; OK changes only edited fields
The dialog shows the selected frame's options, with an inset field per
side, and sends only what the user changed, so unequal insets survive.
The rule weight is read in points.
* Column rules: tint, horizontal offset and top/bottom insets; IDML import and export
Text Frame Options gains Tint %, Top Inset, Bottom Inset and Horizontal
Offset for the rule, and object.textFrameOptions and document.inspect
take and report them. IDML reads the ColumnRule attributes of
TextFramePreference on frames and object styles and writes them when a
rule is set.

* PDF: PDF/A exports keep placed PNG, JPEG, GIF and WebP images by writing them without interpolation (#71)
* Tables: new tables take their paragraph's direction, and the Table panel sets a table's direction (#100)
* Text: stories made in a right-to-left-bound document fill their columns from the right (#100)
A text frame's text area starts at the inner edge of its stroke: the
frame edge, then the part of the stroke inside the frame, then the
inset, on all four edges. A centred stroke takes half its weight, an
inside stroke all of it and an outside stroke none. A stroke without a
colour (or with no weight) doesn't count.
Composition, hit testing and vertical frames all take the text area
from the frame, so they agree. Graphics frames, wraps and the frame's
bounds are unchanged, and type on a path, which has no inset, ignores
the stroke as well.
Trailing spaces and drop caps both join the placed line; hit testing checks
the drop cap first, then the closest line (hit_line). hit_char also picks
the drop cap's character under the point, so a double click on the cap
selects from it (the follow-up both PRs named).

Resolve conflicts with the CJK/Arabic work: trailing spaces follow the line
only in left-to-right paragraphs without right-to-left glyphs (layout_line
now takes the bidi info); style linking moves to ScopedFonts so the
document's own fonts count (FontDb delegates to scope 0); threading keeps
the receiving story's direction and Vertical Type, and frames split off by
threading or removed from a thread keep theirs.

Resolve conflicts with the CJK/Arabic composition work: line metrics keep
the first-baseline tops and add the CJK alignment shift; the CJK line
reference adjustment applies before baseline-grid snapping; layout_line
takes the bidi info and the drop cap is spliced in after it; vertical text
is now the story's direction (FrameSpec::vertical); IDML insets use main's
validated inset_spacing over the object style chain; format's JSON upgrade
(vertical frames) and model upgrade (format v2 defaults) both run.

IDML names some languages by locale code
(AppliedLanguage="$ID/de_DE_2006", "$ID/nl_NL_2005") beside names such
as "English: USA" and "Spanish: Castilian". language_tag maps any locale
code (ll, ll_CC, ll-CC, with a reform year after them) to its BCP 47 tag
(de-DE, nl-NL; kept once per process, at most 512 distinct tags), ignores
IDML's $ID/ prefix, and knows Spanish: Castilian (es-ES) and Swiss French
and Italian. The stored name stays as written, so IDML round trips are
unchanged.
What depends on the language now goes by the tag: typographer's quotes
(by language subtag; Swiss regions take guillemets), English
hyphenation and spelling (is_english), Korean word breaking and the CJK
fallback chains (ja-JP, ko-KR are Japanese and Korean whatever the
region).
A character the applied font lacks is drawn as that font's missing-glyph
box (its .notdef, gid 0), on screen and in PDF, and Preflight lists the
characters by font ("Missing glyphs in <family> <style>: …", an error,
at most 20 named). A .notdef without an outline is drawn as a hollow box
across its advance, so a missing character never disappears. PDF draws
.notdef glyphs as paths, which PDF/A and PDF/UA accept. Kenten marks are
set in their text's font the same way.
The document setting Draw Missing Glyphs from Fallback Fonts
(DocSettings::glyph_fallback; Preferences > Composition,
document.preferences {glyphFallback}, undoable) draws them from fallback
fonts instead (the language-aware chains, then any font; kenten marks
from a fallback font, else a bullet). It is off in new documents and
IDML imports and on in files saved before it existed, which keep
drawing as they did. A missing font's substitute always uses fallback
fonts. The composition cache's signature includes the setting. Tests
whose Arabic comes from a fallback font turn the setting on.
language_tag ignores case and punctuation and recognises Chinese in its
common spellings and locale codes (Simplified Chinese, Chinese
(Simplified), zh_CN, zh-Hans; Traditional Chinese, zh_TW, zh_HK,
zh-Hant), and Japanese and Korean locale codes (ja_JP, ko_KR).
Typographer's quotes for Chinese and Japanese follow the tag, so every
spelling takes the same quotes. IDML import keeps the name as written.
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.
Korean is set word by word (KLREQ): Hangul, in any language, and Han
ideographs in Korean-language text take no line breaks between
characters, so lines break at spaces. Glyphs carry their language tag
for this. A paragraph attribute, koreanCharBreaks (type.para, paragraph
styles, Paragraph Style Options > Justification), breaks between
syllables instead. It is DesignCraft-only; IDML doesn't carry it.
A paragraph's kinsoku set decides which breaks it forbids, and Korean
still breaks at spaces under one.
Kinsoku still holds, also when the single-line composer has to split a
word wider than the measure: the split moves back so no line starts
with closing punctuation.
The character's language (as IDML names it) maps to a BCP 47 tag
(designcraft_doc::language_tag) and is the shaping context's language
on the harfrust buffer, so OpenType locl applies for every language in
the list (Japanese, Chinese, Korean, Turkish, ...), not only Arabic,
Persian, Urdu, Hebrew and English: other names used to reach the
shaper as they were written, which it doesn't know, so their locl never
applied. designcraft_fonts no longer maps names itself. The word-shaping
cache is keyed by the tag. Chinese: Simplified and Chinese: Traditional
join the language list (plain Chinese stays, tagged zh); Simplified
Chinese takes curly quotes, Traditional Chinese corner brackets.
Drop caps get the Drop Cap Detail options as paragraph attributes: Align
Left Edge (on by default) and Scale for Descenders (kept and
round-tripped; no layout effect yet). With Align Left Edge the drop
cap's origin moves left by its first letter's left side bearing so its
ink starts at the indent, and the lines beside it start where its
advance ends. Right-to-left drop caps are unchanged.
Drop cap characters are counted as code points, extended to the end of
the grapheme cluster so a letter keeps its combining marks.
IDML imports and exports DropcapDetail (bit 1 Align Left Edge, bit 2
Scale for Descenders). DropCapStyle is still imported but no longer
exported: IDML applies the drop cap's character style through a Dropcap
nested style instead.
Format 1 documents keep their drop caps unaligned where nothing set the
option. Paragraph Style Options > Drop Caps has Align Left Edge and Scale
for Descenders checkboxes.
Paragraph rules can be in Text Color: they take the colour of the
paragraph's first character (rule above) or last character (rule below).
That is the default, and IDML maps RuleAboveColor / RuleBelowColor
"Text Color" both ways.
Defaults for what a file leaves unset, in the model and in IDML import:
text frames auto-size from the centre, numbered lists don't continue
across stories, and alternating table and table style fills start
Black 20 % then None 100 %. Kashidas (DefaultKashidas / KashidasOff)
import and export. A tint of -1 is the colour's own tint everywhere tints
are imported (underline and strikethrough, footnote rules included), and
tints are capped at 100 %.
Format 1 documents load as saved: they wrote rules, text frame options,
lists and table fills in full, so nothing relied on the old defaults.
Keep Lines Together now defaults to "At Start/End of Paragraph" (2/2):
new paragraphs, and IDML that sets Keep Lines Together without
KeepAllLinesTogether anywhere in the style chain, keep lines at the
start and end instead of moving the whole paragraph.
The native format is now version 2. Loading a version-1 document pins
"all lines" where that document resolved it from the old default (the
start of each paragraph style chain that leaves it unset, and
paragraphs whose style is missing), so saved documents keep their
layout.
A document keeps one data source, the placeholders that point at its
fields, and the last merge layout. Empty merge state is omitted from
the file. New documents and IDML imports start with that state empty.
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.
