# The 250-line cap, enforced on push as well as at commit time. The local
# pre-commit hook can be skipped (a fresh clone that never ran `pre-commit
# install` has no hooks at all), so the cap needs a second gate that no one
# can forget to install.
#
# Deliberately a SEPARATE workflow from release-apk.yml: a file that grew too
# long should fail lint, not block publishing an APK.
