Mobile first multi-step form

What are you most proud of, and what would you do differently next time?

This is my first time doing a multi-step form. I ran into a few issues but I'm not unhappy with the final product.

What challenges did you encounter, and how did you overcome them?

I used the zod library for the form validation. I totally didn't use it the correct way. I ended up using it in a hacky sort of way. I later saw a better method of using it for the same type of validation together with the useForm hook. If you have any comments or observations regarding that or any other thing, please let me know.

What specific areas of your project would you like help with?

Your feedback and suggestions are welcome always. Thanks
