dipankarchettri/PACT ? reverse-engineered prompt

Build me a web app called PACT for educators to track how their students are doing with coding practice. I want a clean dashboard where I can add students by their LeetCode and GitHub usernames, check that the accounts are valid, and then see their progress in one place.

The app should pull in stats automatically, show each student’s scores, problem solving activity, submission trends, language breakdown, and a simple overall performance score. I also want charts that make it easy to compare students, a way to sort and search the list, and a button to export the data as CSV.

Please include automatic daily refresh so the numbers stay current, plus a manual refresh option for each student. If possible, add a section with smart insights that points out weak topics and suggests practice problems, and a simple badge or milestone system for things like top solver or streaks.
