/* Home — infinite category slider (parts/home-categories-slider.php)
 *
 * Implementation:
 * - Viewport uses native overflow-x scrolling (touch swipe + mouse drag built in).
 * - JS pushes scrollLeft each frame for the infinite marquee effect and
 *   wraps it when it crosses the half-width point (two duplicated groups).
 * - Prev/next arrow buttons snap one card at a time.
