<!-- apps/viewer/public/__test__/embed-host.html —— P4b Task 4 e2e 专用宿主夹具页。
  仅测试资产（计划约定：不入 viewer 生产路由），模拟第三方站点引入
  {VIEWER_ORIGIN}/embed/v1/loader.js：查询参数 ?slot=&lang=&interval=&position=
  透传为 loader data-*；?poll= 同源写入 iframe contentWindow.__embedPollMs 加速
  轮询断言（__viewerPollMs 惰性读取同一约定）。本页不设 CSP——宿主真实 CSP
  要求（script-src/frame-src {EMBED_ORIGIN}）见 packages/embed-loader/README-embed.md。 -->
