   美车汇 AI 智能客服 · QQ 风格主题 (qq-theme.css)
   --------------------------------------------------------------------------
   设计说明：
     - 在 theme.css 之后加载，靠更高的选择器优先级覆盖，不改动插件原文件
     - 头部用 QQ 蓝渐变；对方气泡白色、自己气泡 QQ 蓝，带小三角（QQ 聊天窗特征）
     - 自己的头像在 DOM 里是空的 .pc-service-left，用 CSS 伪元素补一个"我"
       （这样无需修改 aihelper.js）
     - 覆盖 theme.css 中 .pc-service-left{position:absolute} 的定位，改为 flex 布局
   QQ 主色: #12B7F5
