Convert your PR to draft if tests are pending to be added.

Also, please run the pre-commit hooks before making commits. I'm catching a lot of issues that are supposed to be caught and fixed by the pre-commit hooks.

Run pre-commit run --all once you've installed the pre-commit hooks.

Left a bunch of comments, mostly styling related.

Logic wise code seems alright, if you're stuck on styling let me know and I'll try pitching in some code.
