Two paths for skinned GLBs with no live body driving them:
- animation clips in the GLB (e.g. Mixamo moves) are parsed (rotation/
translation channels, nlerp sampling) and looped at the effect speed;
- without clips, a beat-locked procedural dance drives the FK targets:
arms pump on alternate beats, hips sway, head nods, knees bounce, with
a free-running metronome keeping the groove between detected beats and
bass scaling the amplitude.
