/* ---------------- 客服悬浮窗（036）----------------
 *
 * ⚠️ 这套样式**必须放在本文件**（公共页只加载 site.css）。
 *
 * 历史坑（2026-10-17 修复）：这些规则曾被"统一"到 theme.css，理由是"避免两份定义互相覆盖、
 * 改了不生效"。但 theme.css **只在后台 adm_head 里加载**，公共页的 pub_head 从不引它 ——
 * 结果不是"以 theme.css 为准"，而是**公共页上这套样式整体消失**：
 * 真机实测 `.contact-fab` 算出 position:static / 34×23px，被排到页面最底部，
 * 用户看到的就是"客服悬浮窗不见了"。
 *
 * 现在归属明确：几何/配色/层级一律在本文件；theme.css 里只留一条指回这里的注释。
 * 层级关系：mask 59 < fab 60 < panel 61（遮罩必须低于面板，否则面板点不动 —— 曾踩过）。
