Watch-side features developed on the AMOLED-2.06 and shared across all boards:
- BLE command channel (…0005, notify watch→PC) via ble_send_command(); the
watch stays "dumb" and the daemon maps commands to Home Assistant.
- Battery detail screen + protective low-voltage cutoff; power HAL gains
battery_mv() / shutdown(), with battery_est.{h,cpp} for the time-left anchor.
- Home screen: dynamic 2-column button grid driven by the desktop config
(RX "btns" labels); tap notifies {"cmd":"btn","i":N}.
- Dimmer screen: IMU tilt-joystick over the light's brightness / color temp.
imu_hal_read_accel() added to the HAL (real on 2.06/2.16, no-op elsewhere);
streams absolute {"cmd":"bri"|"ct","v":..}; daemon seeds the dial via "dim".
Per-board tilt axis is calibrated with the DIM_CALIB overlay (off by default).
Multi-board fix: enable LV_FONT_MONTSERRAT_20/28 on the 2.16, 1.8 and C6 envs.
Shared ui.cpp uses these glyphs for the launcher tiles and back chevron, so
those three boards had failed to compile since the Phase-2 UI landed. All four
envs now build clean. README: correct the Windows pairing name to "Clawdmeter".
