/*
 * 方案 D「Talky Glass · 液态玻璃」外壳样式（web-shell）：登录 / 注册、整体布局与导航、会话列表、联系人、群组、
 * 群资料 / 群管理、我的 / 设置 / 外观 / 隐私，以及通用弹窗、底部弹层、按钮、输入框、开关、提示条。
 * 只用 play-tokens.css 的 --pf-* 变量（深色、8 种强调色、降低透明度自动跟随）。
 * 选择器统一以 html[data-theme] 开头：与 theme-dark.css / appearance.css 的 html[data-theme="dark"] .x 同级，排在后面所以生效。
 * 设计稿：TalkyMobile/docs/ui-redesign/v2/parts/set-d.html（.scr-d）。
 *
 * 玻璃件两种：
 *  - 悬浮控件（顶部玻璃按钮、底栏、搜索圆钮、语言胶囊、弹出菜单）用实时模糊 blur(20px)；
 *  - 大面积卡片 / 列表 / 设置格用 --pf-glass2 静态玻璃（不模糊），手机浏览器滚动不卡。
 * 高光描边、顶部光泽都是 ::before / ::after 伪元素，一律 pointer-events: none，不挡点击。
