- Remove static/idle color from entire stack (storage, API, processing, UI, CSS, locales) - Simplify device power button to turn-off only (send black frame, no toggle) - Send black frame on serial port close (AdalightClient.close) - Fix settings modal serial port dropdown showing WLED devices due to stale deviceType Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
