/* ============================================================
   站内客服 · 领取入口 + 对话面板
   ------------------------------------------------------------
   定位：入口不是「帮助」，是「领 100 元 / 首条免费」的办事窗口。
   所以入口是一张带承诺的卡片，面板第一屏是两条身份路径，而不是三个功能菜单。
   - 配色与站点一致：火色 #FF4A1C / 墨 #0B0D14 / 细线 #E4E7EE
   - 桌面：右下角卡片；手机：贴底胶囊（不压正文、好点）
   - 不依赖 site.css 的变量，首页与内容页都能直接用
   @version 1.7.0（新增对话内领券卡片样式；券只在联系客服后出现）
