Do we have more type information than Any?

Thanks for the review!

Do we have more type information than Any?

Ideally the type hint should be list[list[figure]]. However there is something unexpected going on with both of the mypy stubtests (the independent job and the pre-commit job).

When using list[list[figure]] the independent job fails although the pre-commit job passes, with

error: No overload variant of "gridplot" matches argument types "list[list[figure]]", "int | None", "int | None", "str"  [call-overload]

Ignoring the error with a # type: ignore[call-overload] causes the pre-commit job to complain about the unused ignore statement. Unfortunately, I am not able to find a type hint (other than list[list[Any]]) that lets both these tests pass.
