aiswaryasur/Microsoft-certificate-tracker ? reverse-engineered prompt

Build me a single page Microsoft Learn certificate tracker that feels polished and easy to use on desktop and mobile.

I want users to be able to explore learning paths for AI and Data Science, Cloud Computing, Cybersecurity, and Development, then mark lessons or courses as completed and see their progress update right away. Please include clear progress bars for each path and an overall completion view so people can tell how far along they are at a glance.

Also add a simple sign up and log in flow on the front end so the app can simulate a user profile and remember the current state during the session. After someone finishes a step, show a helpful next step recommendation with a short explanation of why that path makes sense, like an AI powered learning assistant. Make the layout responsive, clean, and friendly, with smooth interactions and a modern Microsoft Learn style. If you need to, look up current docs online for any details that would help.
