   § 2. 蛍エフェクト — レイヤー構造
   ──────────────────────────────────────────────────────────────────
   問題: hero__fireflies を #scene-bg の中に入れると
         scene-bg の opacity(0〜0.50) が継承され、
         fireflyGlow(0.12〜0.95) が 0.05〜0.38 に圧縮 → 明滅が見えなくなる。
         CSS opacity 継承は子要素から上書き不可。

   解法: hero__fireflies を scene-bg と独立した兄弟要素にし、
         自身の opacity:1 を保つ。
         コンテンツセクションを z-index:3 に引き上げることで、
         暗い背景色がUIエリアの蛍を視覚的に覆い隠す。
         → 背景画像が透けているエリアにのみ蛍が見える。

   z-index 階層:
     #scene-bg (z-index:1)             ← 図書館背景画像
     .hero__fireflies (fixed, z-index:2) ← 蛍 / TOPと同一アニメ
