+/**
+ * Horizontal scroll track with mandatory snap (no Swiper).
+ * Full-bleed track via responsive gutters; next slide peeks on the right.
+ *
+ * @author Cédric Andrietti
+ *
+ * @param $item-selector - slide items (default: direct li children)
+ *
+ * Custom properties (optional overrides on the scroll container, set before the include):
+ * --horizontal-scroll-gap  - flex gap (falls back to --column-gap, then theme spacing)
+ * --horizontal-scroll-peek - visible part of the next slide (defaults to gap + xs spacing)
+ *
+ * Example:
+ *
+ *     .my-track {
+ *         @include breakpoints(sm, max) {
+ *             --horizontal-scroll-gap: var(--column-gap);
+ *             @include horizontal-scroll-snap;
+ *         }
+ *     }
