/* CampusTrace — "liquid glass" layer.
   Loaded after style.css; it only re-skins the explorer (profile, gallery,
   voices, atlas, compare, dialogs). Tokens first, components after.
   Rules: text on glass keeps >= 4.5:1 (ink #f4f5f8 on an effective ~#15161c),
   motion is transform/opacity only, and every effect has a reduced-motion
   and a no-backdrop-filter fallback. */
