# One pipeline for both subprojects, because they ship from the same commit.

# The web app is built twice and only twice — once per base path — and every
# consumer downloads an artifact instead of rebuilding:
#
#   build (root, base "")  -> deploy-firebase, preview-firebase
#   build (gh,   base /loto) -> deploy-pages
#
# The Android app is native Kotlin/Compose and builds independently of the
# web bundle (it mounts web/static/audio straight from the checkout).
# Tags are handled by android-release.yml, which builds standalone.
