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.

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.
Cached Skia paragraphs bake absolute image/gradient shaders at layout
time. On move, clones reuse those paragraphs while painting at the new
selrect, so glyphs move and the fill stays put. Record the paint origin
when layout is built and translate the canvas when painting from cache
so shaders track the text. Also sync bounds before update_layout so
fills bake against the current container.
Emit clipped `<image href>` for fills with a registered media URL instead
of Skia base64 embeds. Register URLs from the frontend and exporter via
store_image_url. Cover rect, path, frame, and text (glyph clip) cases in
SVG export tests.
Closes#11383
* ♻️ Share text layout paragraphs across modifier clones
Store Skia paragraphs in Rc so TextContentLayout::clone keeps the
cached layout for rotate/pan modifiers. Add layout.clear() and treat
needs_update as paragraphs-empty only.
* ⚡ Reuse cached Skia paragraphs when painting text
Add try_paint_from_layout_cache to paint from TextContent.layout when
versions match, skipping ParagraphBuilder rebuild and layout on each
frame. Wire into the layered text path for plain fills without strokes
or effects.
* ⚡ Paint plain text directly onto Current
Extend can_render_directly for stroke-free text and skip the empty
save_layer in draw_text when no stroke-group opacity is set. Plain text
paints into Current without the Fills/Strokes blit.
Shapes and text with stacked solid fills were exported without fill
attributes because merge_fills builds a Skia shader that SkSVGDevice
does not serialize. Draw each fill layer separately for SVG export,
bottom to top, matching the classic exporter.
Closes#11466
* ✨ Add text and @font-face to WASM SVG export
Emit selectable <text> elements and inject @font-face rules that
reference the font URLs registered at load time. Text fill bypasses
save_layer wrappers that SkSVGDevice drops. Text strokes are deferred
to a follow-up PR.
* 🐛 Strip trailing commas from Skia SVG text positions
Skia's SVG backend appends a trailing comma to per-glyph x/y lists.
Firefox rejects the malformed attribute and drops glyph positioning,
making exported text vanish or mis-render.
* ✨ Add headless wasm render backend to the exporter
* ♻️ Move render-wasm bridge to common and split wasm builds
* 🔧 Upload builtin font variants in the wasm exporter
* ♻️ Move shared font and resources utils out of render_wasm
* ⚡ Fetch only the exported roots in the wasm exporter
* ⚡ Bound save_layer rects in the vector export path
