/* ---------------- 移动端 ---------------- */
/* 手机端面板直接铺满可视区：
   1) 用 position: fixed + top/right/bottom/left 定位，不再用 100vh / 100vw。
      移动端 100vh 是「地址栏收起」时的大视口高度，比真实可视区高，面板又贴底，
      多出的高度会把顶栏标题和右上角按钮顶到屏幕外，看起来就是「显示不全」；
      100vw 同理（含滚动条宽度），可能比可视宽度宽。
   2) 加上刘海屏 / 全面屏的安全区适配，避免底部提示被系统手势条压住。
   3) 输入框 16px 字号，防止 iOS 聚焦时自动放大页面。 */
