/* ── Motion layer ────────────────────────────────────────────────────────────
 * All keyframes, scroll-reveal helpers, and futuristic micro-interactions
 * live here so the structural CSS files stay readable.
 *
 * Authoring notes
 * ───────────────
 * • Page-load entrance is staged by `.stage` (parent) + `.stage-item`
 *   (children with `--i: <index>`) so a single class on a container fires
 *   a clean stagger across its children.
 * • Anything tagged `.reveal` starts hidden and animates in when an
 *   IntersectionObserver in animations.js adds `.reveal--in`.
 * • `.shine` paints a soft moving highlight across glass surfaces.
 * • `.spotlight` cards listen for `--mx` / `--my` CSS vars set by JS to
 *   render a cursor-following radial light.
 * • Honour `prefers-reduced-motion: reduce` at the bottom of this file —
 *   everything collapses to a static, accessible state.
