| name | moon-hop |
| description | Bounds forward in big, slow, floaty low-gravity moon hops with long hang time, via a translating sequence with high root.y arcs. Use when a command mentions moon hop, low gravity hops, astronaut bounce, floaty jumps, moon bounce, or bound like on the moon. |

moon-hop
Big, slow, floaty two-foot bounds with lots of hang time and arms drifting out — like low gravity.
Composes: bend-knees + move-leg + balance-and-posture
How
- Use a
sequence with loop:false. Frame root is ABSOLUTE; compute the travel axis from state.position+state.faceDeg (0=+Z, 90=+X). The example assumes origin facing +Z.
- Each hop: gentle push, long high float (
root.y~0.5, toes pointed, arms out), soft land; advance z a lot per hop.
- Slow
durationMs (~2600) for the floaty feel.
Example
- "do moon hops" ->

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.
