/* ⚠️ 本轮关键修复:这里之前是 z-index:10,比下面 .bottom-nav 的 z-index:20 还低。
   .tip-sheet 是评论区/编辑资料/账号绑定/作品播放等所有底部弹层共用的基础类,
   z-index 比底部导航栏低,意味着弹层最下面一截(通常正好是评论输入框、
   保存按钮这些最关键的功能按钮所在的位置)会被常驻的底部导航栏盖在下面——
   这正是"评论区/个人资料弹层功能键被遮盖"反馈的根因,不是 overflow/滚动本身的问题,
   而是这块区域从一开始就在视觉上被压在导航栏下面,滚动到底也够不着。
   现在把所有弹层统一提到 40,确保在底部导航栏(20)之上;上传进度遮罩层
   (upload-overlay)本来就该盖住一切,相应地也从 30 提到 50,继续保持在最上层。 */
