/**
 * One-shot arrival: `active` starts true and goes false for good.
 *
 * Callers hang a mount animation off `active` and call `end` from
 * `animationend`. The timer is not a duplicate of that event — it is the only
 * thing that ends the intro when the animation never runs at all, and there are
 * three ordinary ways for that to happen:
 *
 * - `prefers-reduced-motion`, where the stylesheet cancels the animation
 * - `forced-colors`, where the animated element is hidden outright
 * - a background tab at mount, where animations are throttled or skipped
 *
 * Without it, anything gated on the intro being *over* — the Ask Leo chip's
 * resting glow, for one — would stay in its pre-arrival state permanently for
 * exactly the users least able to afford a missing affordance.
 *
 * Pass an `id` when the animating element can unmount and come back inside one
 * page load, and the arrival should not play again when it does. Call this hook
 * in the component that owns the animated element rather than an ancestor that
 * outlives it: an ancestor starts the clock while the element is absent, and by
 * the time it mounts the intro is already spent on nothing.
