/*
 * 2026-04-19 — global empty-state styling.
 *
 * Yii2 GridView (BaseListView) renders <div class="empty">No results found.</div>
 * when the dataProvider has 0 rows. Out of the box it's small grey text
 * floating outside the table — visually invisible. This file styles it to
 * match the canonical .closo-empty-state seller-side block.
 *
 * Loaded by:
 *   - assets/AppAsset.php (admin layout)
 *   - assets/AppAssetSeller.php (seller layout — applies to GridViews
 *     embedded in seller views)
 *
 * Also augments the existing .closo-empty-state with a hint slot for
 * search-aware messages and a clear-filter affordance.
