BortoneA/cognito ? reverse-engineered prompt

Build me a simple web app for managing Cognito login flows, with a clean front end and a small Node server to support it.

I want a page where someone can sign in, sign up, and handle the usual account steps like verification and password reset in a straightforward way. Keep the UI modern and easy to use, with clear forms, friendly messages, and basic loading and error states.

If you need current details for any Cognito related setup, feel free to look up the latest docs online. Make it work well as a small starter project I can run locally and extend later, with the front end and server wired together cleanly.
