/*
 * Photo comparison cards — shared responsive 3-card row.
 *
 * Same behaviour as the approved homepage "Guía de tejidos" block (home.css
 * .ed-fabrics__grid / .ed-fabric-card), extracted as a reusable component:
 *
 * - >= 1024px: 3 cards in one row, no scrolling.
 * - 768–1023px: one horizontal row, ~2.2 cards visible.
 * - < 768px: one horizontal row, one card (86%) + a peek of the next.
 *
 * Native overflow-x + CSS scroll-snap only (no library, no autoplay, no
 * dots/arrows). The row bleeds to the viewport edges (negative gutter
 * margins + matching padding) so the peek reaches the edge, and snaps to the
 * content edge via scroll-padding. Only the track scrolls horizontally —
 * never the page. assets/js/photo-cards.js only brings a keyboard-focused,
 * partially visible card fully into view.
 *
 * Markup:
 *   <div class="ed-photo-cards [ed-photo-cards--portrait]">
 *     <a class="ed-photo-card" href="…">               (or <article class="ed-photo-card ed-photo-card--static">)
 *       <span class="ed-photo-card__media">
 *         <img class="ed-photo-card__img" …>
 *         <span class="ed-photo-card__badge">…</span>     (optional)
 *       </span>
 *       <span class="ed-photo-card__body">
 *         <span class="ed-photo-card__title">…</span>   (h3 when the card is not a link)
 *         <span class="ed-photo-card__meta">…</span>     (optional)
 *         <span class="ed-photo-card__desc">…</span>
 *         <span class="ed-photo-card__cta">… <icon></span>
