+// Command server runs the PilotVault API Server. It is the single entry point
+// the Fly App (drone/telemetry uplink) and the Web App / API Web Panel talk to.
+// It keeps live device state in memory, fans telemetry out to dashboards over a
+// websocket, and proxies authentication to a PocketBase kept behind it.
