/* ---------- Motion ----------

   Three rules hold everywhere below:
   1. No element is ever hidden by a base rule. `opacity: 0` only ever appears inside a
      `from` keyframe, so if a timeline is inactive or a feature is unsupported, the
      content simply renders statically instead of disappearing.
   2. Every animation lives inside `prefers-reduced-motion: no-preference`.
   3. Reveals move on the block axis only, so nothing can widen the page in RTL or at 320px.
*/

/* Cross-document view transitions were tried here and removed: the transition overlay
   keeps intercepting pointer events for the length of the fade, so a visitor clicking
   two links in quick succession loses the second click. Not worth it on a site whose
   whole point is working without scripting. */
