/* =========================================
   Neptune – "Coverflow"-Karussell: Bandmitglieder ziehen im Kreis
   von rechts nach links durchs Rampenlicht.

   Konzept: Statt eines selbstgebauten Scroll-Lock-Effekts kommt hier
   das altbewährte, native "Coverflow"-Muster zum Einsatz (wie man es
   von vielen Bildergalerien kennt): Ein ganz normales horizontal
   scrollbares Element (.carousel-viewport) mit CSS scroll-snap. Der
   Browser übernimmt dabei komplett Touch, Momentum/Trägheit und das
   Einrasten auf die mittige Karte. JS (assets/js/members.js) liest
   nur die Kartenposition aus und legt die 3D-Rotation/Skalierung
   (rotateY / scale / opacity) obendrauf.

   Respektiert "prefers-reduced-motion": Dann gibt es keinen
   Coverflow-Effekt, sondern eine ruhige, statisch untereinander
   angeordnete Liste (.stage-track--static).
