+
+There are several render styles: `bars` (default, scrolling peak history),
+`line` (oscilloscope), `vu` (single level meter), `spectrum` /
+`spectrum-mirror` (frequency bars), `blob` (smoothed filled area) — these six
+render below the art and are mutually exclusive — plus `circular` (a ring
+around the play/pause button) and `glow` (the art pulses with loudness),
+which are independent toggles that can combine with a below-art style and
+with each other. Set `WAVEFORM_TYPES` (comma-separated) to expose more than one; a
+small picker then appears letting each visitor choose their own combination,

+visitor picks anything. Leaving both unset behaves exactly like before this
