/* list-page.css — reusable list/archive page skeleton
 *
 * Shared by watch.html and stories.html (Tasks 17 & 18).
 *
 * Owns: .list-layout (rail + grid), .list-rail (sticky sidebar with
 * search/sort/facets), .list-grid (4→3→2→1-up), .list-card (the card
 * shell — visual variants like .video-card or .story-card belong on
 * the consuming page), .list-search input, .list-chips chip group,
 * .list-chip pill, .list-sort dropdown, .list-result-count live
 * counter, .list-load-more button, .list-empty no-results state.
 *
 * Brand tokens (--ha-navy, --ha-red, etc.), .video-frame /
 * .play-badge, and the global breakpoints all live in shared.css —
 * we extend them, never redefine.
 *
 * No emoji. Squared corners. Brand colors only.
