Registration state wasn't cleared on WiFi disconnect — device would skip re-registration and publish on stale topic paths. Also re-resolve MQTT hostname on broker disconnect in case IP changed. 30s hardware WDT reboots device if loop() stalls. Removed: unused ESPmDNS include, lastPublishedLevel tracking, lastHeartbeatTime, HEARTBEAT_INTERVAL_MS, ADC_MAX, ADC_VREF.

Device runs a web server on port 80 after WiFi connects. Push firmware with: curl -F "firmware=@firmware.bin" http://dusa.local/update No reverse connection (unlike espota), so no workstation firewall needed. mDNS init is idempotent — safe across WiFi reconnects.
