/* ---------- Entrance motion ----------
   Motion is now JS-driven, opt-in per page paint. The
   [data-reveal] attribute is retained for future use (we leave
   the hooks in place) but no CSS rule binds to it by default —
   content is visible immediately, which is the right floor for
   a print-set page like this. If we ever want to bring back the
   scroll-revealed fade, it goes here. */
