/* Motion primitives for the marketing theme.
 *
 * Contract:
 *  - Everything degrades to fully visible, unanimated content when JavaScript
 *    is unavailable. The reveal classes only hide content once `theme.motion.js`
 *    marks the document with `data-mkt-motion="on"`.
 *  - `prefers-reduced-motion: reduce` disables every transform and transition
 *    here, including the parallax layers.
 *  - Only `transform` and `opacity` are animated, so the compositor does the
 *    work and layout is never invalidated.
