    // Create client with HTTP/3 support
    jvr_client_config_t config = {
        .prefer_http3 = true,
        .prefer_http2 = true
    };
    jvr_client_t* client = jvr_client_create_with_config(&config);
    
    // Create and send request
    jvr_request_t* request = jvr_request_create("GET", 
        "https://api.github.com/users/github");
    jvr_response_t* response = jvr_client_send(client, request);
    
    // Handle response
    if (response && response->status_code == 200) {
        printf("Success! Body: %.*s\n", 
               (int)response->body_size, response->body);
    }
    
    // Cleanup
    jvr_response_destroy(response);
    jvr_request_destroy(request);
    jvr_client_destroy(client);
    
    return 0;
}
