 *   - Every rounded surface is `.sq` (a continuous corner, see squircle.js).
 *     Only true circles and capsules use border-radius.
 *   - Motion moves `transform`, `translate`, `scale` and `opacity` — never
 *     layout — on spring easings from core.js.
 *   - Presses respond on pointer-down; releases spring back.
