Regex Stateful Test Motion Study

Use [minimal JavaScript snippet], [runtime version] and [expected repeated-call behavior]. Create a 12-second animation of a regex cursor advancing and then being explicitly reset between repeated calls. Base success/failure badges on the supplied execution trace; do not invent engine behavior.

Confirm required reference images and timing inputs are present before generating. Keep objects, identities, spatial relationships and light direction consistent. Render the clip when video generation is supported; otherwise supply a timed shot list, reference checklist and generation-ready prompt, labeled as a production plan. Do not claim rendered output without an actual file. Check the opening, transition and final frame against the stated counts and geometry.
