/* motion, shared with the homepage
   ---------------------------------------------------------------------------
   Reveal on enter: an element starts slightly low and transparent and settles
   once, the first time it scrolls into view. Plain CSS transitions driven by a
   single IntersectionObserver. Nothing is tied to scroll position, so nothing
   fights the reader's scroll.

   NOTHING IS EVER HIDDEN UNLESS THE SCRIPT IS RUNNING, deliberately. Every
   rule is gated on html.motion-on, and only motion.js sets that class: it adds
   it before the body paints, observes [data-reveal], adds `is-visible` on
   entry, and does none of it under prefers-reduced-motion. If the file fails to
   load, the class is never set and every [data-reveal] element is simply
   visible. index.html carries the same script inline.

   The numbers below are the homepage's, on purpose: a reader moving from the
   landing page to one of these should not meet a different, smaller motion.
