; LilyGo T3-S3 -- ESP32-S3 + SX127x LoRa + SSD1306 128x64 OLED + microSD.
; The remote debug bridge: UART <-> telnet(:23)/WebSocket, GPIO reset/wake,
; SD logging (NTP-dated), OLED status. NOTE: ESP32-S3 has NO Bluetooth Classic,
; so HAS_BT_CLASSIC is NOT set here (telnet + WebSocket replace SerialBT).
; Pins marked CONFIRM must be checked against your actual board wiring.
