- Add LoRa idle/sleep/receive-window helpers and use short RX windows for ACK/time sync - Schedule sender time-sync windows (fast/slow) and track RX vs sleep time in debug - Lower sender power (80 MHz CPU, WiFi/BT off, reduced ADC sampling, unused pins pulldown) - Make SERIAL_DEBUG_MODE a build flag, add prod envs with debug off, and document changes
