Readings paint above the line box, outside the glyph metrics. The text
bounds joined the emphasis marks only, so an auto-width text with ruby
or Zhuyin and no emphasis exported with the top of its reading cut off.
Measure the ink of the readings with the code that paints them and join
it to the content and auto-width bounds.

Zhuyin, Pinyin and emphasis marks over horizontal text were placed
against an em box bottom-aligned to Skia's tight glyph rect, which spans
the hhea ascent and descent. In CJK faces the descent reaches past the
em box, so Zhuyin columns sat about 0.17 em below their base, and over
annotations relied on a hand-tuned clearance.
Place them against the ideographic em box (OS/2 typo metrics) of the
font that shaped each base, centred on the line baseline, the same
metrics vertical text uses for upright glyphs.

Each ruby reading attached its lowest ink to the base, which suits kana
but not Latin letters: the descender of "y" lifted "yǒu" above "liáo"
over 友聊, and under ruby moved with ascenders and tone marks.
Western letters in a reading now take the font's descent (over) or cap
height (under) instead of their ink, so Pinyin and romaji readings share
one baseline and descenders stay clear of the base. Upright glyphs keep
the ink edge.

Add distributed alignment to text styles, sidebar controls, CSS export,
and the Plugin API. Spread characters across horizontal and vertical
lines, including the final line, while preserving graphemes and annotations.
Keep fractional line heights consistent across painting, hit testing,
selection, and text paths to prevent baseline drift between lines.
Add tests for distribution, nonbreaking text, and fractional line geometry.

Retain legal line starts at the original wrap width before allowing an
indivisible punctuation or annotation unit to overflow together. Share the
layout plan and alignment offset across painting, editing and exports.
Cover mixed styles, nonbreaking controls, graphemes, annotations, alignment,
strokes and resize. All 666 renderer tests and both WASM builds pass.

Add typed one-character Zhuyin readings with upright right-side symbols
and separate neutral and non-neutral tones in both writing modes.
Persist the mode through the editor, WASM bridge and Plugin API. Preserve
annotation clearance and canvas, PNG, PDF and SVG geometry.
Validate syntax and selection boundaries, and cover schema, bridge,
rendering, UI and API behavior. Native IME and reader review remain open.

Carry optional span positions through the schema, WASM header, editor,
Plugin API and CSS output. Expose Chinese controls with language defaults
and independent overrides for horizontal and vertical text.
Reserve automatic clearance per side and stack underlines, ruby and
emphasis. Preserve reading groups during decoration edits and retain
canonical position values in DOM editor style data.
Add protocol, geometry, editing and API tests, including the prior Japanese
mixed-font gutter behavior. Verify both WASM targets and live exports.

Add named Chinese punctuation presets and a Korean keep-words mode for
horizontal and vertical layout. Preserve the saved spaces-only mode and
keep source offsets stable through safe emergency wrapping.
Apply bounded CJK spacing and justification, expose the new choices in the
sidebar, and document preset bounds and remaining release checks.
Verify renderer, frontend, common and exporter tests, both WASM builds,
and sample save/reload plus PNG, PDF and SVG exports. Existing CI failures
remain documented in the layout notes.

Choose paragraph layout rules from an optional language tag. Pass language
to horizontal and vertical shaping, add basic Chinese punctuation rules,
and add experimental Korean spaces-only wrapping.
Keep text boundaries grapheme-safe and preserve paragraph profiles across
editor splits and merges. Add reproducible font fixtures for localized
glyphs and regression tests for the shared WASM protocol and layout paths.
Validation: renderer, common JVM/JS, frontend and exporter tests pass.
Both WASM targets build. Full CI still reports baseline lint and format
errors and one backend multipart-upload test failure.

Lay out horizontal and vertical Japanese text with kinsoku, ruby,
emphasis, warichu, tate-chu-yoko and proportional font features.
Carry the layout through glyph paths, SVG export and text selection.
Update the Rust and ClojureScript binary formats together, including
the editor bridge and headless exporter. Resolve CJK fallback fonts
and add renderer tests and font fixtures.
