Typography.kt resolved Fraunces, Inter and JetBrains Mono through the Play Services font provider, which fetches them over the network on first use. Same rule-164 problem the web client had, with a second failure mode on top: the provider is absent entirely on devices without Play Services, so the app fell back to the platform default and stopped looking like Minstrel — quietly, with no error. The five static instances now live in res/font, vendored by the same tools/vendor-fonts.py that produces the web bundle. Both clients draw from one list of faces so they cannot drift apart. Cost is ~0.86 MB of APK; the runtime path is removed rather than kept as a fallback — the ui-text-google-fonts dependency, its version-catalog entry and the provider certificate hashes in font_certs.xml are all gone. Two things about fetching TTFs that are worth writing down, because both fail by succeeding: Google Fonts picks the format from the User-Agent, and there is no parameter to ask for one. A modern UA gets woff2, which res/font cannot load. The obvious "use an old UA" fix gets EOT — an IE-only format that downloads happily, has a plausible size, and is entirely useless here. An Android 4.4 UA is what actually yields TrueType. css2 also collapses a multi-weight request to 400 for legacy clients, so asking for Medium silently returns Regular: a valid TrueType file that renders at the wrong weight everywhere. Each weight is therefore fetched on its own URL, and the script now asserts OS/2 usWeightClass on every download — that field is the only thing distinguishing the two files. Verified before wiring: all five carry TrueType magic, the 400/500 pairs differ, and their usWeightClass reads 400/400/500/500/400 as declared beside them in the FontFamily. Not covered: there is no guard for this on the Android side. The web equivalent is asserted by no-external-assets.test.ts, but the Android tree has no source-inspection test pattern to follow and no way to falsify one without a local Gradle run.
