/* 翻页转场：雾从画面下方涌上来，在最浓的时候换页，再错峰散开。
   这个故事叫「雾锁大江」，第 3 页的正文就是 thick fog covers the river——
   用雾做转场不是装饰，是把标题演一遍。

   三层雾分工：
     far    最远最慢，蓝灰，给雾"厚度"，也让散开时最晚褪干净；
     near   纯白最快，负责遮干净（换页那一帧全靠它挡住）；
     plume  画面中下部的两团亮部，给雾一点体积起伏，否则三层平铺像一块白布。

   每层都做成 160% 高、上下各溢出 30%。这样雾的羽化上缘在推进过程中会扫过
   画面，推到位时那道软边已经跑到画面外了——换页瞬间顶部不会漏光，也不必为了
   遮住顶部而把上缘做成硬边（硬边看起来就是"一块布被拉上来"）。 */
