Firmware does R→UV→Y→IR sequential scan autonomously. Miniprogram
now listens for 4 consecutive ADC notifications, storing each as a
separate spectrum group. Also listens for run_state=IDLE as scan
completion signal. Displays all 4 spectrum groups with PD1-PD7 bars.
Stores full scan data in globalData.lastScanData for diagnosis phase.
- 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
