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.

Upload structural shape attrs (base, children, blur, shadows,
flex, layout-item) via multi-shape `_set_shapes_batch` FFI in
chunks of 512, then apply host attrs with use-shape selection.
* ✨ 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.
