/**
 * E-Potion Product Carousel
 *
 * Shared styles for [ep_new_products_carousel] and [ep_categories_carousel].
 *
 * Architecture:
 *   • Track scrolls horizontally with native CSS scroll-snap.
 *   • Each card snaps individually on touch swipe (mobile UX).
 *   • Arrow buttons & dot indicators advance by viewport-width (one page).
 *   • Cards are absolute-width via flex-basis calc() to guarantee
 *     5-per-row on desktop, 3-per-row on tablet, 2-per-row on mobile.
 *   • Card heights are equalized via flex column + min-height on title
 *     + margin-top:auto on the CTA, so buttons always align at the bottom.
 *
 * Brand: uses --ep-* design tokens with hardcoded fallbacks so the carousel
 * still looks right if loaded before design-tokens.css.
