- Android release signing reads a gitignored key.properties, falling back
to debug keys so contributors can still build --release.
- CHANGELOG.md (human, newest-first) + Fastlane/F-Droid metadata (en/es)
with descriptions derived from docs/intro.md.
- docs/release.md: the by-hand build + manual smoke checklist (no CI yet).
- inventory_scale_test guards the list query against N+1 at 3000 varieties.
