This page isn’t working
localhost sent an invalid response.
ERR_INVALID_HTTP_RESPONSE

Not sure if you want a PR for this series as it would have to apply to all the commits. :)

To fix this, I changed the code in Main thusly:

        String htmlResponse = router.route(request);

        String httpResponse = 
                "HTTP/1.1 200 OK\n" 
                + "Content-Type: text/html\n"
                + "Content-Length: " + htmlResponse.length() + "\n"
                + "\n"
                + htmlResponse;
        
        s.getOutputStream().write(httpResponse.getBytes());
