/**
 * Single-element animation driven by an Integrator simulation, played through
 * the Web Animation API.
 *
 * Lifecycle:
 *   1. `play()` / `reverse()` calls `simulate()` from the current (position,
 *      velocity) toward the target bound, producing a frame list.
 *   2. Frames are converted to WAAPI keyframes; `element.animate(...)` runs them.
 *   3. While playing, `getPose()` interpolates the live position from frames
 *      using `performance.now() - startTime`.
 *
 * Identity for motion matching is the DOM element itself — when a previous
 * animation's pose is handed in via `matchInto`, we look up by element.
