; RemoteRig — Dual-Board Camera Node Firmware
; ============================================
; Each camera node has TWO boards connected via UART:
;
;   ESP8266 (Camera Bridge):   Connects to GoPro AP → HTTP status/control
;   ESP32   (MQTT Bridge):     Connects to travel router → MQTT to hub
;
;   ESP8266 ←──UART──→ ESP32
;   (TX/RX)           (RX16/TX17)
;
; Build:
;   pio run -e esp8266-camera    (ESP8266 D1 Mini — camera bridge)
;   pio run -e esp32-mqtt        (ESP32 Dev Board — MQTT bridge)
;
; Upload:
;   pio run -e esp8266-camera --target upload
;   pio run -e esp32-mqtt --target upload
;
; Filesystem:
;   pio run -e esp8266-camera --target uploadfs
;   pio run -e esp32-mqtt --target uploadfs
