 * motion.css — Site Me motion tokens + states v1.0.0 (2026-06-10)
 * Ships VERBATIM with every Site Me build, linked BEFORE the build's own
 * stylesheet. Never edit per-site — give each build its own motion character
 * by overriding the tokens below in the build's :root, e.g.:
 *
 *   :root { --reveal-duration: 700ms; --reveal-distance: 36px; }   (languid)
 *   :root { --reveal-duration: 420ms; --reveal-distance: 16px; }   (snappy)
 *
 * Every hidden-initial state is scoped under html.js (set by the inline boot
 * snippet) so a no-JS visitor sees the entire page, static. The
 * prefers-reduced-motion block at the bottom is the second guarantee.

   bug). overflow-x: clip kills that bleed without creating a scroll container.
   It must be on BOTH html and body: the root's overflow propagates to the
   viewport and the root's own used value resets to visible, so body has to
   clip its content too (verified empirically in Chromium — either one alone
   still reports horizontal overflow). Scoped under html.js so no-JS rendering
   is untouched; vertical scrolling and position:sticky are unaffected. */
