/* ============================================================
   官网客服聊天窗（2026-10-04 重写）
   ------------------------------------------------------------
   风格：微信 / 企业微信经典款 —— 中性灰消息底 + 品牌蓝出站气泡。

   ★★★ 2026-10-04 修掉一个致命 bug：类名整体错配 ★★★
   旧版 CSS 写的是 .ch-avatar / .cm-text / .cf-send / .cf-btn 这一套，
   但 aio-v2.html 与 aio-v2.js 实际用的是
     .chat-head-main / #aioChatTitle / #aioChatStatus / .chat-icon-btn
     .chat-msg.from-* / .chat-role-label / .chat-bubble
     .chat-foot / .chat-input-row / #aioChatInput / .chat-send-btn
   两边对不上 → 消息气泡、发送键、输入行、角色名全是零样式裸元素，
   页面看起来像"一堆没上色的字"。本次把类名口径统一到下面这套，
   HTML 里也全部改成显式 class（不再依赖裸元素默认样式）。

   位置说明：右下角原本有 #stickyCta（免费试用/预约演示），
   聊天窗排在它【上面】（bottom 更大），两者不重叠。
   颜色令牌沿用 aio-v2.css 的 --aio-*，保证与整站一致。
