- 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.
