- Send scan command: all 5 regions LED on, brightness 128 - Listen for ADC notify (17 bytes) instead of broken queryStatus - Parse and display PD1-PD7 values with visual bars - Show VBAT/battery info - Store scan PD data in globalData for Phase 3 smart adjustment - 8s timeout fallback, stop LED on page unload
