   --------------------------------------------------------------------------
   目录
     1.  主题令牌（:root 暗色 / [data-theme="light"] 浅色）
     2.  基础与重置（盒模型 / 原生控件配色 / 选中 / 滚动条 / 焦点）
     3.  排版、字体栈与工具类（.nf-num .nf-scroll .nf-sticky .nf-split .nf-tip）
     4.  应用外壳（.nf-app .nf-side .nf-nav .nf-main .nf-top .nf-page）
     5.  容器与网格（.nf-card .nf-grid.cols-*）
     6.  统计卡片（.nf-stat-*）
     7.  表格与分页（.nf-table-wrap .nf-table .nf-th-sort .nf-pager）
     8.  表单（.nf-form .nf-field-* .nf-input .nf-select .nf-switch .nf-tags）
     9.  按钮（.nf-btn 及 primary/ghost/danger/warn/sm）
    10.  标签、徽标、等级（.nf-badge .nf-tag .nf-tone-* .nf-level.lv-* .nf-badge-demo）
    11.  弹层（.nf-modal-* .nf-drawer-* .nf-toast*）
    12.  数据展示（.nf-kv .nf-timeline .nf-tree .nf-terminal .nf-progress .nf-code .nf-tabs）
    13.  状态与反馈（.nf-empty .nf-loading .nf-skeleton .nf-error-banner .nf-login）
    14.  通知与用户菜单（.nf-notify-* .nf-user-menu）
    15.  响应式（≤1200px 图标栏 / ≤820px 抽屉 + 单列）
    16.  减少动效与打印
   --------------------------------------------------------------------------
   动效约定：所有过渡 ≤180ms，只有 2 个一次性关键帧（nf-fade-in / nf-pop），
   全文件不存在任何 infinite 循环动画；加载遮罩与骨架屏均为静态视觉。
