/* ===========================================================================
   商家客服面板（Views/Shared/_SellerChatPanel.cshtml，脚本 seller-chat.js）：详情页（问一个项目）和店铺页（问一整家店）共用这一份。
   原来写在 codedetail-v6.css 里，颜色取详情页 .cd-page 上的变量；店铺页没有那几个变量，所以每个都带详情页同样的兜底值。

/* 商家客服面板（跟作者的 AI 助理对话）：非模态的 dialog，固定在右下角，盖在小五（z-index 900）上面、
   弹窗（1050）下面 —— 问满了要登录时，登录弹窗得能盖住它。老浏览器不认 dialog 时靠 :not([open]) 藏着。 */
