/* =========================================================
   Carrusel de modelos (portada) - "Selecciona tu modelo Suzuki"
   Reemplaza al acordeón: con 14 modelos los paneles quedaban
   demasiado angostos. Es un carrusel MANUAL (no avanza solo):
   se mueve con las flechas, los puntos, el teclado o deslizando
   con el dedo. El desplazamiento lo hace el navegador con
   scroll-snap; js/model-carousel.js solo maneja flechas y puntos.
