text_vertical/flow.rs held both the JLREQ column passes and the planner
the plain, Chinese and Korean policies use. Move the pairwise planner,
spacing and alignment to flow/pairwise.rs; the JLREQ passes stay in
flow/mod.rs with the flow types both share.
Also list the CJK renderer modules and their new names in
docs/cjk-layout.md.

TextLayoutPolicy had nine flat variants that mixed language, Chinese
region and Korean wrap. It is now Plain, Japanese, Chinese(ChineseRegion)
or Korean(KoreanWrap), and the layout code asks it named questions
(uses_jlreq, plans_breaks, keeps_overlong_units, reopens_overlong_words,
bounded_justify, needs_joiner, normalizes_western_spaces,
uses_clreq_positions, ...) instead of comparing variants.
Paragraph parses its language once, when the language or the Korean wrap
changes, and copies the policy to its spans. Span code no longer builds a
policy from the tag with a dummy Korean wrap, and the emphasis and
underline positions take the policy instead of a Chinese flag.
A LanguageTag parser now serves both the layout policy and the CJK font
choice. It also accepts '_' as a separator, as the font choice did, so
a tag such as "ja_JP" now selects the Japanese policy.
The korean-wrap byte decodes through a new exported RawKoreanWrap enum
(Syllable=0, SpacesOnly=1, KeepWords=2) with the same byte values.

Recover merged annotation styles on the base character's own line, using
separate UTF-16 line anchors and UTF-8 style keys. Include emphasis marks
in horizontal text bounds so standalone exports keep each mark whole.
Add regression coverage for adjacent readings, wrapped text, emoji line
anchors, raster output and export bounds across all text grow modes.
Verify 670 renderer tests, formatting and both WASM builds. Add four
editable showcase examples and check their layout and exports.

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.

Support typed character and group readings through the shared ruby model.
Expose Chinese labels, presentation controls and selection guards without
changing Japanese controls or generating pronunciation.
Preserve complete source ranges for glyphs sharing a combining cluster.
Add pinned horizontal and vertical tone-mark fixtures and editor tests.

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.

Drop the separate :wasm-export flag and wasm-export/v1 feature. Single
export, clipboard PNG, plugins, and batch :is-wasm now key off
render-wasm/v1 alone. The exporter trusts :is-wasm for headless WASM
and always keeps a worker pool ready.
