/* ==========================================================================
 * 一覧UIの改善
 *
 * 旧実装の課題と対応:
 *  1. カードに面がなく、ホバーが u-hover-trans（全体を opacity 0.6）だけだった。
 *     画像もろとも薄くなるため「押せる」感じが弱い。
 *     → 白い面＋枠線のカードにし、ホバーは浮き上がり＋枠線の強調＋画像の拡大に変更。
 *  2. flex + 固定幅のため、タイトルの行数差で1行内のカード下端がバラついていた。
 *     → grid + align-items: stretch で1行のカード高さをそろえる。
 *  3. 日付が .l-body の 0.16rem を継承し、タイトル 0.18rem とほぼ同じ強さだった。
 *     → 0.13rem に落として、視線がタイトルへ向くようにする。
 *  4. カード内のカテゴリが絞り込みボタンと同じピル形で、押せそうに見えて押せない。
 *     → 角丸を小さくしたラベル表現にし、押せる絞り込みピルと形で区別する。
 *  5. キーボード操作時のフォーカスが見えなかった。
 *     → :focus-visible のアウトラインを追加。
 *  6. 絞り込んでも件数が分からず、結果の手応えがなかった。
 *     → 絞り込みボタンに件数、一覧の上に該当件数を表示。
