- Winamp style spectrum analyzer instead of the face while music plays,
using audio_spectrum from randybb/esphome-components
- head touch: tap starts the assistant, stroking shows an in-love face;
SI12T sensitivity raised so the pads actually trigger
- battery (AXP2101) and wifi indicators, ear icon while listening
Voice assistant satellite with animated face on the CoreS3 display:
- power rails, IO expander resets and servo power as in the M5 BSP
- mic and speaker share one I2S bus, so the mic is released before playback
- AW88298 volume limited to the audible range (0.5-1.0)
- partial display redraws, status screen until Home Assistant connects
- battery and wifi indicators, listening icon
- camera converted to JPEG on demand, no periodic frames
