kaungmyathan22/nextjs-budget-app — reverse-engineered prompt

Build me a simple personal budget app I can actually use day to day. I want people to be able to sign up and log in, then add income and expenses, put them into categories, and see their current balance update automatically. There should be a clean dashboard that shows a quick summary of money coming in, money going out, and what is left. Make it feel polished and easy to use on both mobile and desktop.

Please use this repo as the base and finish whatever is needed so it runs locally with a database setup from the env file and migrations. If something is missing, wire it up in a sensible way instead of overcomplicating it. Keep the interface modern and straightforward, with forms and tables for managing records. If you need to, look up current docs online for anything unclear.
