// 游戏发行沙箱的真实浏览器检查：把「探针包」发布到本地发行网关，再用 Chromium 以
// `sandbox="allow-scripts"` 的 iframe 打开它，断言不透明来源下能载入什么、被挡掉了什么。
//
// 需要：本地 dev 栈（SpacetimeDB + api-server）+ 管理员账号 + playwright。
//   npm install --prefix %TEMP%\genarrative-pw --no-save --no-package-lock playwright
//   E2E_PLAYWRIGHT_DIR=%TEMP%\genarrative-pw
//   E2E_CHROMIUM_EXECUTABLE=<ms-playwright 里的 chrome.exe，可省略>
//   E2E_ADMIN_USER=... E2E_ADMIN_PASSWORD=... npm run check:game-distribution-sandbox-e2e
//
// 覆盖：ES module 与同包资源能在 opaque sandbox 下载入；运行期 storage 兼容层可用；
// 外站 fetch / WebSocket 被挡；document.cookie / 父文档 DOM 都拿不到；顶层跳转和弹窗被挡；
// 敏感权限（定位）被拒；同时核对发行网关的 CSP / nosniff / CORS / Cookie 403 策略。
