# Build a versioned Linux CLI release tarball (see `make package`), the
# Pebble watchapp (see `make watchapp`), and the Android app (see `make
# android`) on every push/PR, plus on-demand via the Gitea "Run workflow"
# button. Runs inside build-image (see ../../build-image/Dockerfile,
# built/pushed via ../../build-image.sh and ../../upload-image.sh), which
# bundles the Pebble SDK and the Android SDK/NDK alongside the C
# toolchain. Unlike the CLI/Pebble build path, the Android build still
# needs network access at job runtime (Gradle/AGP/androidx dependency
# resolution) - see the root CLAUDE.md's Android section.
