SQLModel que `id` es la **clave primaria** en la base de datos SQL (puedes aprender más sobre claves primarias de SQL en la documentación de SQLModel).

    Nota: Usamos `int | None` para el campo de clave primaria para que en el código Python podamos *crear un objeto sin un `id`* (`id=None`), asumiendo que la base de datos lo *generará al guardar*. SQLModel entiende que la base de datos proporcionará el `id` y *define la columna como un `INTEGER` no nulo* en el esquema de la base de datos. Consulta...
