What movement explains:
Applications in scope:

| Trigger | Starting and resting compositions | Duration / travel / easing | Stop or interruption | Quiet alternative | Owner and check |
|---|---|---|---|---|---|
| First arrival | | | | | |
| Deliberate replay | | | | | |
| Ordinary control response | | | | | |

## Completed teaching specimen

- First load: three complete stepped red forms, already settled.
- Replay: move inner groups vertically by up to 18 CSS pixels; 880ms per part; 70ms stagger; cubic-bezier(.2,.8,.15,1); one run.
- Fixed placement stays on outer groups and cannot be overwritten by animation.
- Stop: restore the completed arrangement immediately.
- Quiet: no travel under OS reduced motion or site Motion off; replay disabled with an explanation.
- Meaning: one repeated behavior relates separate parts; no content depends on completion.

## Acceptance

- [ ] Inspect first, final, quiet and interrupted states.
- [ ] Reach controls with the keyboard; keep focus visible.
- [ ] Check at the smallest relevant viewport and real text lengths.
- [ ] Change visual expression without changing the motion preference.
- [ ] No automatic replay on scroll; no hidden essential content.
- [ ] Name the source, export, implementation and update owner for each application.
