   1. 所有图表都用统一的 `.ring` 圆环组件，跟 .big-donut-wrap 大环同款
   2. 圆环弧颜色用 var(--primary) CSS 变量 → 主题切换浏览器自动重渲染，无需 JS 监听
   3. 圆环轨道统一 #e5e7eb 实色灰（100% 不透明，无任何 alpha 叠加）
   4. 数字 ease 计数（保留动画）；stroke-dashoffset 1.2s 补间（保留动画）
   5. 进度条/折线图/cls-* 整组已废弃（彻底删除相关代码） */

   【根因】`body.theme-jade .layout` 特异性 (0,2,1=2类+1元素) 高于 `.layout.jade-student`
   (0,2,0=2类)，所以之前所有 `.layout.jade-student { display:block }` 全被 grid 压掉，
   layout 始终是 `210px / minmax(0,1fr) / 280px` 三列 grid，banner/focus 作为 grid 子项
   被卡在列宽里（1366 屏只有 ~810px）。v707.3~v707.11 的所有 grid-area 折腾都白费。
   【解法】选择器必须带 `body.theme-jade` 前缀拉高特异性到 (0,3,1)：
   每个区块（topbar/banner/focus/footer）都是 width:100% 的全宽条，
   区块内容用 `padding: 0 max(16px, calc((100% - 1380px)/2))` 或 max-width 限宽居中。
