   CAROUSEL

   - Estructura:
     .carousel (contiene todo)
       .carousel-viewport (ventana visible, puede hacer scroll-x en modo snap)
         .carousel-track (lista flex de .slide)
           .slide (tarjeta de película)
       .carousel-btn.prev / .carousel-btn.next (controles)
       .carousel-dots (indicadores)
   - Para alternar entre modos:
     • Coverflow: usar js/carousel.coverflow.js y mantener overflow hidden.
     • Scroll-snap: usar js/carousel.snap.js y permitir overflow-x en viewport.
