* fix: serve the UI typefaces from the instance
The page loaded its faces from a third-party host on every visit, including sign-in. Bundle those faces and stop allowing remote font and style sources.
* fix: keep the full subset coverage of the served typefaces
Bundling the faces left only the latin and latin-ext subsets declared, so
Cyrillic, Cyrillic Extended, Greek, Greek Extended, Vietnamese and the
symbols2 block rendered in a system face instead of the selected one.
Declare every subset the installed packages publish for the faces the
Appearance preference offers, with the range the package subsets each face
to, and hold the declarations to those ranges and to representative
characters per script in the font test.
backend/tsconfig.json had no incremental setting, so every tsc run
re-checked the full project from cold. The two frontend tsconfigs
already declared a tsBuildInfoFile path under node_modules/.tmp/ but
without incremental: true the file was never written, and the path
itself sits inside node_modules where npm ci wipes it on every fresh
install — neither of which actually persists incremental state.
Add incremental: true to all three configs and drop the broken
tsBuildInfoFile overrides. TypeScript's default places the buildinfo
next to the tsconfig (e.g. backend/tsconfig.tsbuildinfo); the root
.gitignore already covers *.tsbuildinfo so nothing leaks into git.
Local cold-vs-warm tsc --noEmit on the backend dropped from ~3.0s
to ~1.4s — ~2x speedup on the warm path. CI builds are still cold
because runners do not cache the buildinfo between jobs; that is a
separate workflow change.
