b9591ce9bb feat(power): 1Hz chunked light-sleep; meter backoff; log throttling 
- 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

532a9154b1 Calibrate battery ADC and document LiPo curve 
- Add BATTERY_CAL config and debug logging for raw ADC samples
- Use LiPo voltage curve (4.2V full, 2.9V empty) for % mapping
- Document battery calibration, curve, and debug output in README

e045673a3a Fix OLED autosleep timing and battery sampling cadence 
- Track last OLED activity to avoid double timeout; keep power gating on transitions
- Copy TZ before setenv() in timegm_fallback to avoid invalid pointer reuse
- Add BATTERY_SAMPLE_INTERVAL_MS and only refresh cache at batch start when due
- Keep battery sampling to a single ADC read (Arduino core lacks explicit ADC power gating)

9c5b8fcdb4 Reduce sender power draw (RX windows + CPU/WiFi/ADC/pins) 
- 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
