/**
 * WebChat 桌面端样式 v3.2.1
 * 与移动端 mobile.css 完全隔离：本文件使用 --primary/--bg 等变量与 .app/.sidebar 等类名
 * 移动端使用 --m-* 变量和 .m- 前缀类名，详见 mobile.css
 * v3.2.0: 未读角标从列表项右侧移到昵称旁边（昵称行内 flex 排列）
 * v3.2.1: 修复侧栏 tab 上的角标被挤到第二行（tab 内容强制同排不换行）
 * v3.3.1: 通讯录面板：新增 .ct-cell「新的朋友」入口行样式
 * v3.3.2: 通讯录面板：新增 .contact-list/.ct-item 朋友名单样式
 * v3.3.3: 发起群聊：视图内成员勾选步骤样式 .group-select*
 * v3.3.4: 设置改为右侧视图：删除 .me-submenu/.me-sub-item，新增 .settings-list
 * v3.4.0: 个人资料可编辑：新增 .avatar-img 头像图片、.pv-edit 操作按钮行、.pv-nick-edit 昵称输入行
 * v3.4.1: 「我/退出登录」菜单图标改为图片：新增 .menu-icon-img
 * v3.4.2: 好友资料页底部「发送消息」按钮：新增 .pv-send
 * v3.6.2: 长消息撑满内容区：.msg-row max-width 72%→100%（气泡仍按内容收缩），并移除窄屏 86% 覆盖
 * v3.6.3: 长消息对侧再留一个头像宽：.msg-row max-width 改 calc(100% - 42px)
 * v3.6.4: 注册邮箱+找回密码：新增 .auth-forgot 链接、.auth-hint 提示、.fp-sent 成功盒
 * v3.6.8: 资料页编辑行下方新增「关闭」链接：.pv-edit-close
