// 静态预览验收：证明 WE 模拟面板**不依赖调试服**，且是**右边缘滑出**的。
//
// 为什么要有这个测试：
//   ① 面板曾经只在调试服注入时才存在。用户要求 GitHub Pages 预览也能弹出它——
//      静态托管没有调试服，所以必须由 `--with-sim` 把驱动**注入 index.html**。
//   ② Pages 把站点放在 `/<repo>/` **子路径**下。驱动若用根绝对路径 `/scripts/…`，
//      在子路径下必然 404。所以这个测试刻意把分发挂在 `/repo/` 前缀后面服务，
//      而不是挂在根上——挂根上测不出这个错。
//
// 用法：node tools/checks/verify-static-preview.mts [分发目录名]
// 前提：已经 `pnpm build --with-sim`。
