[M1-S9] Animation state machine without rubbery transitions #31

User story

As a player, I want the hero's animation to change cleanly between idle, walk, run and jump, so that nothing pops or melts.

Acceptance criteria

• Idle → walk → run switch only on shared contact frames, through the bridge clips
• Stepped 12 fps playback; strong poses held
• An idle variant plays at random after 5 s standing still

Design and references

09 – Smooth, not rubbery.

Dependencies

Needs the movement sheets and the atlas exporter. Suggested owner: Vatsal (player and combat code).

Verification

Record a GIF of start/stop/run/jump on the preview and step through it frame by frame.
