Wire WiFi creds via .env + build-time injection, add heartbeat reporting Adopts the weather-display pattern: .env file parsed by tools/load_env.py and injected as -D compiler flags. WIFI_NETWORKS uses "SSID:password" format. ESP32 now sends a heartbeat POST after each display update so the server can track frame status for the HA integration.
