// e2e: 数据大屏两种形态 —— 首页班级入口 + 单班独立大屏（含后退锁定 / 顶栏控件收敛）
//
// 覆盖点：
//   1) 无 ?class= → dash-home：仍显示班级下拉，顶栏出现"选择考试 → 点卡片进入"文案
//   2) ?class=X   → dash-class：顶栏隐藏班级选择 / ← 主系统，页面内不出现回首页的链接
//   3) 后退锁定：lockHistory() 只在 IS_CLASS 时挂，首页不受影响
//   4) 卡片渲染：直接把 dashboard.php 里的 clsCardHtml 抽出来跑，断言卡片结构与跳转参数
//   5) 公开访问：带 ?class= 的班级大屏免登录，且接口只回该班数据（其它班级不泄漏）
//
// 运行：node tools/test-dashboard-nav.js
