- Replace delay() with light_sleep_chunked_ms() in sender idle path (100ms chunks preserve UART FIFO safety at 9600 baud) - Add ENABLE_LIGHT_SLEEP_IDLE build flag (default: on, fallback: =0) - Meter reader task: exponential backoff on consecutive poll failures (METER_FAIL_BACKOFF_BASE_MS..MAX_MS) to reduce idle Core-0 wakeups - Configurable SENDER_DIAG_LOG_INTERVAL_MS (5s debug / 30s prod) - Configurable METER_FRAME_TIMEOUT_CFG_MS, SENDER_CPU_MHZ - New PlatformIO envs: lowpower, 868-lowpower, lowpower-debug - Add docs/POWER_OPTIMIZATION.md with measurement plan and Go/No-Go
