vish006-coder/MERN_Notes ? reverse-engineered prompt

Build me a simple notes app where users can sign up, log in, and keep their notes in one place.

I want a clean home screen with a top nav, a main area for notes, a search box so I can quickly find a note, and a footer. After logging in, I should be able to create, view, edit, and delete notes easily. Make the forms for login and registration feel friendly and easy to use, with basic validation and clear error messages if something is wrong.

Use a modern, polished layout that looks good on desktop and mobile, and keep the styling consistent across the app. If you need to check anything, look up current docs online. Please wire up the front end and backend so the app actually works end to end, and make sure the whole thing runs smoothly with the usual start command.
