 * 滚动稳定性修正 —— 消除下滑/回弹时的闪烁
 * ------------------------------------------------------------
 * 实测原因：
 *   ① 之前为"防重建白闪"给每张卡片加了 GPU 层提升（translateZ(0)），
 *      卡片一多会造成图层抖动 → 滚动时反而闪。现在卡片不再重建，这层
 *      提升已无必要，去掉。
 *   ② 顶栏带 backdrop-filter 又是 sticky，滚动时容易和内容抢合成层 →
 *      给它独立的稳定图层。
 *   ③ 公告跑马灯每帧动 → 固定在自身图层，避免全页重绘。
 *   ④ 彻底禁止页面级 overscroll（含横向回弹）→ 下拉不再触发刷新。
