 * The Downloads area's own stylesheet: the index, a listing and the submission form.
 *
 * It is a page's worth of CSS rather than the board's, which is why it is a file of its own
 * and why `views/layout/header.php` loads it on those three pages and nowhere else. The
 * vocabulary is the same as `assets/forum.css` — the same tokens, the same radius, the same
 * one-card-shadow rule — so a heading, a button and a card on this page look like the ones
 * beside them, and a board that restyles itself restyles these too.
 *
 * The layout is the React build's, class for class in spirit:
 *
 *   * the heading with its three shortcuts and the lede under it;
 *   * the kind tabs, which are the Files / Add-ons / Themes filters;
 *   * the featured shelf, a slider of up to six cards, three of them in view;
 *   * a two-column body — a 240px sidebar of category, top-resource and review cards, and
 *     the resource list itself, with the dashed empty state it shows when there is nothing
 *     to list.
 *
 * Everything is inside `@layer legacy`, like the board's own sheet: an *unlayered* rule beats
 * a layered one whatever its specificity, so a file that skipped the layer would silently
 * outrank every rule it was written to sit beside.
