user-synax/snapbio ? reverse-engineered prompt

Build me a polished link in bio web app called Snapbio where people can sign up, sign in, and create their own public profile page at a custom username URL. I want users to be able to edit their name, bio, avatar, and social links, then drag and reorder links, hide or show them, and pick from a few nice themes and icons. The public page should look clean and modern on mobile and desktop, with smooth animations and a strong visual design.

Also add a simple dashboard where users can see their profile, manage links, switch themes, and view basic click stats. If a user is marked as Pro, unlock extra themes and analytics like top links and click counts. Use MongoDB for storing users, links, and analytics, and make the whole thing feel production ready with good form handling, auth, and a nice landing page that explains the product. Look up current docs online if you need to.
