/**
 * Carousel
 *
 * A flexible carousel / slider for cycling through content, built on
 * embla-carousel-react (the official shadcn carousel pattern). All parts are
 * consolidated into this single file and wired through a React context that
 * holds the embla api.
 *
 * Tailwind class strings are kept 1:1 with the Vue registry's carousel so the
 * two frameworks render identically.
 *
 * @example - Basic carousel with images
 * <Carousel>
 *   <CarouselContent>
 *     {images.map((img) => (
 *       <CarouselItem key={img.id}>
 *         <img src={img.src} alt={img.alt} className="w-full h-full object-cover" />
 *       </CarouselItem>
 *     ))}
 *   </CarouselContent>
 * </Carousel>
 *
 * @example - Carousel with navigation controls
 * <Carousel opts={{ loop: true }}>
 *   <CarouselContent>
 *     {slides.map((slide) => (
 *       <CarouselItem key={slide.id}>
 *         <SlideContent content={slide} />
 *       </CarouselItem>
 *     ))}
 *   </CarouselContent>
 *   <CarouselPrevious />
 *   <CarouselNext />
 * </Carousel>
 *
 * @example - Vertical carousel
 * <Carousel orientation="vertical">
 *   <CarouselContent>
 *     {items.map((item) => (
 *       <CarouselItem key={item}>{item}</CarouselItem>
 *     ))}
 *   </CarouselContent>
 * </Carousel>
