# Manual signed-APK build for the standalone Android app (RuStore). Runs ONLY from master, ONLY on
# workflow_dispatch with confirm=build — the same deliberate-manual shape as prod-deploy.yaml, never on
# a PR. It builds the native-flavoured SPA, bundles the offline dictionaries into the APK assets, and
# assembles a release APK, uploaded as a run artifact (RuStore upload stays manual for the MVP).
#
# Signing degrades gracefully: with the ANDROID_KEYSTORE_* secrets present the APK is signed; without
# them build.gradle produces an UNSIGNED release APK (so a dry run still proves the whole pipeline).
# The keystore is a publication prerequisite — see deploy/README.md (Android build/release runbook) and
# ANDROID_PLAN.md §E. The toolchain is self-provisioned here (JDK 21 + a cached Android SDK), so the
# runner host needs nothing pre-installed.
