/**
 * 双端全路由冒烟断言（PRD §2.3 成功标准 ③ / SPEC NFR-06）
 *
 * 用法：
 *   npm run build && npm run smoke
 *   # 或指定已运行的地址： SMOKE_URL=http://localhost:4200 npm run smoke
 *
 * 行为：
 *   1. 起一个静态服务器托管 `dist/fmode-app-v2/browser`（或复用 SMOKE_URL）
 *   2. 用桌面（1440×900）与移动（390×844）两个上下文跑全路由断言
 *   3. 断言项：路由可达 / 无未捕获页面错误 / 无横向溢出 / 关键交互可用
 *   4. 结果落 `test-results/smoke/`（截图 + 汇总 JSON）
 *
 * 🔴 数据源说明：冒烟在 **演示数据模式** 下跑（`useMockData: true` 构建），
 *    以便在无真实后端凭据时也能验证 UI 结构与路由。
 *    真实数据链路另由 `npm run smoke:live`（需登录态）覆盖。
