- Language gains lo-LA, labelled ລາວ in every catalog, so the new
translation can be chosen.
- Two Lao keys under stale names now use the catalog's names, and the
touchpad option added since gets its Lao label.
- The web build gets a Lao font (Noto Sans Lao, generated like Thai) and
routes Lao and Thai drawing text to their fonts; Thai had a font but
was never routed to it.

Preload one language-aware font resource across the interface, drawing text, and navigation labels.\n\nRender the navigation cube, ring, outlines, and labels through a 4x MSAA target.
The web build has no system-font access, so CAD text in non-Latin scripts
(Cyrillic, Greek, CJK, …) rendered as nothing — build_fallback was a hard
None on wasm (#141). Instead, ship per-script Noto subsets under web/fonts
(one alphabet per file, SIL OFL 1.1) and fetch them lazily over HTTP the
first time a drawing uses that script, then outline glyphs with ttf-parser.
- web_font: Script enum + script_of (char → script font), a per-script
store with lazy fetch, and a pending queue drained by the app loop.
- CJK is split by language (chinese/japanese/korean). Han ideographs share
code points but differ by language, so the shared block is routed by the
document's $DWGCODEPAGE (932→JP, 949→KR, GB/936→CN); kana is always
Japanese, Hangul always Korean. Re-tessellates when the language changes.
- build_fallback (wasm) outlines from the fetched subset; clear_fallback_cache
lets glyphs that missed while a font was in flight reappear on load.
- PollWebFonts subscription (web only) + WebFontLoaded message drive fetches.
- Trunk copy-dir serves web/fonts; nothing is bundled into the native binary
(desktop keeps using system fonts).
