* **`400 - 499`** son para responses de "Error del Cliente". Este es el segundo tipo que probablemente más usarías.
    * Un ejemplo es `404`, para un response "Not Found".
    * Para errores genéricos del cliente, puedes usar simplemente `400`.

    * An example is `404`, for a "Not Found" response.
    * For generic errors from the client, you can just use `400`.
