/**
 * AI Community Page Builder — Community Carousel
 *
 * Styles for the [cpb_community_carousel] shortcode. One clean, neutral,
 * understated style: a featured image with the community name beneath it.
 *
 * Layout uses CSS scroll-snap on a flexbox track (native touch-swipe on
 * mobile for free). Cards-per-view is driven by a single custom property
 * (--cpb-carousel-per-view) flipped at each breakpoint: 4 desktop / 2 tablet
 * / 1 mobile. Arrow / accent colors use the GeneratePress global color
 * variables (--accent, --accent-2) with sensible fallbacks.
 *
 * @package AI_Community_Page_Builder
 * @since   1.6.0
