In worktrees without rootfs.vfs, Vite failed the module graph before the test page initialized, leaving the runner waiting for readiness with no actionable diagnostic. Lazy-load the rootfs URL only for legacy/default-rootfs browser boot paths, let explicit-VFS pages serve/build without the artifact, and make the MariaDB browser runner fail fast on page load, request, and HTTP 5xx boot failures.
