Build me a simple web app called SmartEduBot for students who want help with college prep and placements.

It should feel like a friendly chatbot where users can log in or register, then ask questions about DSA, aptitude, mock interviews, and placement guidance. I want a clean responsive front end, a chat style interface, and a secure backend that connects to OpenAI for answers. Please include JWT based authentication, basic login and signup screens, and make sure the app can be deployed easily on Railway or something similar.

Use plain JavaScript with Node and Express, and keep the app easy to run locally with an env file for the API key and secret. If you need to check current docs for anything, go ahead and look them up. Also make the UI simple and polished enough for a college student to use right away on mobile or desktop.
