/* ===========================================================================
   OceanMind — „Der Abtauchgang"
   Die gesamte Seite ist ein Tauchgang: Oberfläche (0 m) oben, −40 m unten.
   EIN durchgängiges Unterwasser-Design — es gibt bewusst keinen Hell/Dunkel-
   Schalter mehr; die Tiefen-Dramaturgie (hell → dunkel) IST das Design.

   Die Hintergrundfarbe interpoliert app.js (rAF) durch DEPTH_STOPS auf dem
   fixen .ocean-Layer. Fließtext liegt deshalb IMMER auf Karten mit eigener
   Fläche; nur Überschriften liegen direkt auf dem Verlauf — die Stops sind so
   gewählt, dass der Grund ab Ende des Heros dunkel genug für helle Schrift
   ist (geprüft ≥ 4.5:1, Überschriften ≥ 3:1 gelten ohnehin erst ab 24px).

   Barrierefreiheit unverändert: rem-Schriftgrößen (Panel skaliert 100–140 %),
   data-contrast/readable/underline/motion-Zustände, RTL über logische
   Eigenschaften. Bewegung: JEDE Animation hängt an den zwei globalen Gates
   (prefers-reduced-motion + html[data-motion=off]).
