* `Field(index=True)` le dice a SQLModel que debe crear un **índice SQL** para esta columna, lo que permitirá búsquedas más rápidas en la base de datos cuando se lean datos filtrados por esta columna.

    SQLModel sabrá que algo declarado como `str` será una columna SQL de tipo `TEXT` (o `VARCHAR`, dependiendo de la base de datos).
