The lazy-route recovery cannot help when the browser aborts a module of the static import graph: nothing of the app runs, the root stays empty, and the only trace is a console error. A Web E2E run hit this right after a page reload, when four modules of the shell failed with net::ERR_NETWORK_CHANGED and the shell never rendered. An inline script in the HTML entry now listens for the error event of the module script and reloads the page once, guarded by a session flag that the entry module clears after a successful boot. The existing preload recovery stays in place; it only covers Vite's chunk preloads of production builds. A new E2E spec aborts one module request during boot and one lazy route request, and expects the sign-in page to render in both cases.
