   第七十一轮（2026-09-24）：遮罩层「滚轮穿透」修复
   ----------------------------------------------------------------------------
   现象：弹窗/浮层打开后，鼠标在它上面滚轮，**背后页面被滚走**（弹窗内容装得下、
         内部没有可滚动区域时必现；录屏见「提示词二次改写稿」弹窗）。
   原因：遮罩自身不是滚动容器 ⇒ 滚轮沿祖先链上溯到 body/html，把背景滚走。
   修法：① 让遮罩自己成为滚动容器（overflow-y:auto）—— 滚轮先交给它；
         ② overscroll-behavior:contain —— 它滚不动时也**不许**把滚动传给祖先。
   为什么不用「弹窗打开就 body{overflow:hidden}」那套锁滚：
         那需要维护开/关状态，弹窗异常关闭（报错、被别的逻辑 remove）时
         页面会**永久锁死**滚不动，是这类修法的经典事故。这里纯 CSS、无状态。
   实测（运行期注入仿真，1440x940）：改写稿弹窗 400→0、素材中台 400→0、
         admin 400→0、history 400→0、caption 171→0；同时候选库弹窗内部的
