/* ============================================================
 * 同欣盛 CRM 客户管理系统 - 企业级专业主题 v4.0
 * 设计理念：品牌渐变 × 深色质感侧边栏 × 浅色/深色双主题 × 层级阴影
 * 兼容说明：所有 class 名与 v3.x 完全一致，仅升级视觉与交互表现
 * v3.2：移除侧边栏/菜单项动效（入场滑入/依次浮现/hover 位移/顶部进度条），菜单栏保持原生，其余交互层保留
 * v4.0：新增「浅色 / 深色」双主题体系（html[data-theme="dark"] 一键切换，localStorage 持久化）
 *       深色模式：深蓝黑调色板 × 半透明品牌状态色 × 细腻阴影；质感升级：输入框/滚动条/标签/表格深色适配
 * 引入方式：<link rel="stylesheet" href="/theme.css?v=20260821c">
