   初回描画タイミングに左右されず、終了後は keyframes の効果が外れて
   各要素本来の hover トランジションとも干渉しない。
   fill-mode: backwards により animation-delay（時間差）中も非表示を維持。
   prefers-reduced-motion 時はJS側で無効＋グローバル抑止が効く。
======================================== */
/* transition方式。発火の信頼性はJS側の3点で担保する：
   ① .reveal 一括付与後に強制リフロー（非表示状態を確定させてから表示クラスを付ける）
   ② 時間差（スタッガー）は setTimeout で .is-visible の付与自体を遅らせる
   ③ 表示の最終保証：表示完了後にタイマーで .reveal/.is-visible を除去
     → transition が動かない環境でも必ず素の表示状態に戻る。
       hover トランジションとの干渉もこれで解消 */
