drop-and-roll
Drop low to the ground, roll over (a faceDeg sweep while down), then rise to a stand.
Composes: move-torso + move-leg + balance-and-posture
How
- Use a
sequence with loop:false. Drop root.y low (~-0.7), tuck the legs and torso, sweep faceDeg 0 → 360 while down, then rise to rest.
durationMs ~1600.

Limits & posture
Keep ≥1 foot grounded except at a jump's airborne apex; stay inside human joint ranges and keep weight over the support — see balance-and-posture.
