Please do not merge at the moment. I am still working on the functionality of the code.

Code comments in English please.

If these are just notes to help you understand things and remember what they do, that's fine. Just make sure you remove them all (or rewrite them in English) before you mark the PR as "ready for review".

But if you're using AI, we shouldn't be able to tell. The code should look how it would look if you had written it all yourself; the AI should just be used to arrive at the end result sooner.

Your guess is correct. I am using some level of AI to skip reading all existing code. But I can assure you that once this PR goes out of draft. It will be clean.
