/* =========================================================
   宝锐生物 · AI 助手（前台对话窗口）
   用像素单位、自成一套：窗口是固定大小的浮层，不随页面的 --r 缩放；字体和颜色沿用主题（BioriSans、品牌蓝）。
   位置：悬浮按钮单独在左下角，和右下角「回到顶部」左右对称；窗口从左下角弹出，手机上铺满屏幕。
   吉祥物「宝小锐」（assets/mascot/，2026-11-03 用户选定）：按钮和顶栏里会眨眼、轻轻浮动，欢迎区挥手，回答时思考，出错时抱歉。
   2026-11-03 改版：白色顶栏 + 常驻说明条、欢迎区用实拍底图（biori_ai_cover）、AI 回复不用气泡改成整块、
   相关页面改成列表、快捷问题带图标、输入框和发送按钮合成一个框；进场、消息出现、快捷问题都有动效。
