Rajan-So/DevScribe ? reverse-engineered prompt

Build me a simple but polished blog app where people can sign up, log in, and publish blog posts in Markdown.

I want the site to feel like a real portfolio project, with a clean homepage, a post feed, a page for reading full posts, and protected pages for creating and deleting posts only when the user is logged in. The login state should stay after refresh, and the app should handle auth with JWT so protected actions are actually secure. Use a responsive, easy to use design that looks good on desktop and mobile.

On the backend, set up the API, user accounts, blog posts, and MongoDB storage. On the frontend, make sure the content renders nicely from Markdown, and the app uses a shared auth state so everything stays in sync. If you need to, look up current docs online to make sure the setup is solid and modern.
