/* =============================================================================================
   The welcome drop: our own consent banner (draft "Tropfen 3", 2026-10-25). A drop of light in the
   room, the same language as the drops of the pages (shared/site-drop.css): an aura, liquid light
   along the rim, a body of dark liquid with a pool of light, a breath of gloss. First view round on
   wide windows and a soft pebble on phones; the single choices as a taller pebble. On the legal
   texts a calm capsule at the bottom that does not lock the page. Markup: site_consent.php,
   behaviour: shared/consent.js. Motion only on transform and opacity; none under reduced motion.
