/**
 * Gallery variation: Card Deck Swipe
 *
 * Stacked cards that the user navigates via prev/next buttons (or
 * pointer drag). The IA view module manages the active index and
 * applies a CSS class that drives translation transforms.
 *
 * Reduced-motion: no drag, no slide animation; chevrons-only nav.
 *
 * @package PostFormatsBlockThemes
 * @since 2.1.0
