- android.Dockerfile: build arm64-v8a only (--max-workers=2) → ~48MB APK, ~4x
less compile (the 4-ABI build timed out on the shared prod runner).
- ci.yml: build-apk runs only on version tags (v*), timeout 120m — normal pushes
no longer peg the box; web still auto-deploys on every master push.
- wisp.compose.yml: mount /srv/wisp/wisp.apk read-only so the download survives
web container rebuilds.

- docker/android.Dockerfile: install nodejs (image ships Bun; ci-android-sign.sh
patches build.gradle with a Node script).
- buffer polyfill: whisper.rn -> safe-buffer requires Node's `buffer`, absent in
Metro/RN. Add `buffer` dep, alias it in metro.config.js, set the global in
_layout. Web export unaffected (verified).
Validated locally end-to-end: assembleRelease BUILD SUCCESSFUL, 117MB APK across
all 4 ABIs with librnwhisper.so, signed (CN=Wisp, O=briggen.dev).
