tipsy/profile-summary-for-github ? reverse-engineered prompt

Build me a web app that lets someone enter a GitHub username and instantly see a clean visual summary of that person’s profile.

I want it to pull GitHub profile data and turn it into something easy to understand at a glance, like a nice dashboard with the user’s avatar, name, bio, follower and following counts, public repos, and a few simple visual sections that show their activity and presence in a friendly way. Make it look polished and modern, with a layout that’s easy to share or screenshot.

It should feel fast and simple, with a clear search box, loading and error states, and a good responsive design for desktop and mobile. If you need to look up current docs online while building it, go ahead.
