While on battery (AC0/online=0), sends escalating Pushover alerts at 25/20/15% and at 10% sends a final alert then `systemctl poweroff` (after shutdown_grace so the alert flushes first). Edge-triggered per discharge episode; re-arms when mains returns; plug-out already-low collapses to a single alert (no burst). Pushover token+user live only in /etc/van-battery/pushover.json (0600), seeded from pushover.json.example on first deploy and never committed. Missing/ placeholder creds disable sending but NOT the shutdown — running flat must always power down safely. Publishes /run/van-battery/state.json. Stdlib only.
