    w := wool.New(logger.WithGroup("wool"))
    swg := swagger.New(&swagger.Config{})
    w.GET("/swagger/...", swg.Handler)
    
    srv := wool.NewServer(&wool.ServerConfig{
        Address: ":1323",
    }, logger.WithGroup("server"))
    if err := srv.StartC(context.Background(), w); err != nil {
