// rich readStatus) in the background; this exposes its cache. Live updates ride the
// booth WebSocket (kind:"device-status") — this REST route is the initial load /
// fallback. Any authenticated role may read (operational, not a setup action).
// See wiki/concepts/device-status-monitoring.md, booth-console.md.
