   正本のデザイン: design/chapters.html（デザイン案 v2「絵巻の構成」）
   仕組みの要点:
     画像の章 … clip-path: inset(0) の中で画像を position: fixed。画面に留まり、境目で次の章の画像に入れ替わる
                🔴 祖先に transform を付けると fixed の基準が変わって壊れる
     霞       … 絵巻で場面を区切る横長の雲。章の地の色で前の章へはみ出す。左右は overflow-x: clip で切る
     箱       … 白生地の一反（assets/img/kiji.jpg の織り目＋両端に耳）
