   查56 · 网页端在线咨询组件（web-chat.css）
   --------------------------------------------------------------------------
   设计约束（重要，改样式前先读）：
   1. 配色只用站点既有色：导航蓝 #0a8ddf / 强调橙 #f85100 / 正文 #1f2d3d。
      红色 #e53935 是保留色，只允许出现在「未读角标」上。
   2. 全部类名以 .wc- 前缀 + 低特异性（单类选择器），不覆盖站点既有样式。
   3. 这是「人对人的工单」而不是 AI 客服：不做头像、不做"正在输入"、不做机器人标识。
   4. 页面上同时只应该有一颗橙色实心按钮 —— 当前动作（发送 / 进入咨询）。

   两个浮动子元素让父级 .top-line 高度塌陷成 0（视觉高度全靠 .navbar-inner 的
