sahat/hackathon-starter ? reverse-engineered prompt

Build me a polished Node.js starter app that I can use for hackathons and quick side projects.

I want a clean website with a home page, login and signup, account profile page, password reset, email verification, and social sign in options like Google and GitHub. It should also let users link accounts, turn on two step login, change or delete their account, and upload files. Add a contact form, flash messages, dark mode, and a simple admin friendly layout that looks good with Bootstrap.

Please include basic security protections like rate limiting, CSRF, and captcha, plus support for MongoDB and environment based config. It would be great if the app also has a few sample API integration pages and some AI example pages so I can use it as a starting point for demos. Make it easy to run locally, easy to customize, and ready to deploy. If you need anything unclear, look up current docs online and use sensible defaults.
