Greenbird122/git-vizor — reverse-engineered prompt

Build me a simple static web app called Git Vizor. I want it to feel like a clean tool for viewing a Git project at a glance, without needing a login or backend yet.

Make a landing page that explains the idea, a portal page where someone can enter or choose a repository, a dashboard page that shows sample repo insights, and a trial page where people can click around with demo data. The dashboard should have easy to understand cards and visuals for things like recent commits, branches, contributors, activity over time, and project health. It doesn’t need to connect to GitHub for real right now, but the structure should make it easy to wire that in later.

Keep the design modern, responsive, and friendly. Use plain HTML, CSS, and JavaScript. Make the pages feel connected with consistent navigation, useful empty states, and demo content that makes the product understandable right away.
