# Temporarily restricted to manual dispatch. The GitHub-hosted Android emulator
# (arm64-v8a API 34 on ubuntu-latest) repeatedly fails to reach boot_completed
# within the 1800s timeout, blocking unrelated merges. Re-enable push/pull_request
# triggers once a stable runner/image combination is identified.
