      Client-side 404 redirect guard
      If the page is loaded from a nested file path (for example
      `/example-games/gym/index.html`) the dev server's SPA
      fallback returns index.html which can hide the fact the requested
      file doesn't exist. Redirect such requests to a dedicated
      /404.html page so users see a proper Not Found message instead of
      the app silently booting from the wrong base path.
