/* ===========================================================================
   ÖFFENTLICHE WEBSITE — eigenständiges CSU-Design („Kampagne/Editorial").
   Wird NUR im layout_public.php geladen (nach custom.css + Theme-Overlay)
   und überschreibt dort den Portal-„App-Look" komplett: scharfe Geometrie
   statt runder Karten, Raute als Leitmotiv, kräftiges Farb-Blocking in
   CSU-Blau/Navy, diagonale Sektionskanten, Offset-Schatten, Groß-Typo.
   Das Mitgliederportal bleibt unangetastet (lädt diese Datei nicht).

   Motion: public-motion.js versieht Elemente mit .reveal und schaltet .in
   beim Sichtbarwerden. Ohne JS, unter prefers-reduced-motion und unter
   Playwright (navigator.webdriver) ist ALLES sofort sichtbar.
