Description=Wake Alarm PC fallback alarm tick (rings when the phone stays silent)

[Service]
Type=oneshot
# One tick of DOCS-wake-enforcement.md's table. When it decides to ring it
# rings in THIS process, polling the phone every 20 s, until a session
# starts, an escape arrives or the 30-min cap; while it runs, the timer's
# next minute is a no-op (the unit is still active), so no PID file.
ExecStart=/usr/bin/python -m wake_alarm._fallback --tick
# A ring lasts at most FALLBACK_RING_CAP (30 min); 40 leaves room for slow
# Firebase polls without ever cutting a ring short. SIGTERM becomes
# SystemExit, and the backend (pw-play, or the root ALSA unit) is stopped
# in a finally block on the way out.
