Python itself doesn't do anything with this `Annotated`. And for editors and other tools, the type is still `str`.

But you can use this space in `Annotated` to provide **FastAPI** with additional metadata about how you want your application to behave.

The important thing to remember is that **the first *type parameter*** you pass to `Annotated` is the **actual type**. The rest, is just metadata for other tools.
