/*!
 * XXL-CONF Admin Theme for Bootstrap 5.3
 * ======================================
 * 管理平台主题层：只做「品牌化 + 布局」，组件行为全部由 Bootstrap 5.3 提供。
 *
 *   1. 设计令牌（支持 data-bs-theme 明暗模式）
 *   2. 基础排版
 *   3. 按钮 / 表单 / 校验
 *   4. 卡片 / 表格 / 分页 / 工具栏
 *   5. 弹窗 / 下拉 / 徽标
 *   6. 管理框架外壳（顶栏 / 侧边栏 / 内容区 / 页脚）
 *   7. 业务页面（列表页 / 表单页 / 首页统计 / 登录页 / 错误页）
 *   8. 第三方控件（select2 / CodeMirror / layer / nprogress）
 *
 * 说明：颜色统一走 CSS 变量，`<html data-bs-theme="dark">` 即可整体切换暗色，
 * 页面与脚本不需要任何额外适配。
