Sangamesh1805/Leetcode-Tracker — reverse-engineered prompt

Build me a simple browser based LeetCode tracker to help with DSA prep, especially for a Java focused roadmap. I want it to feel clean and minimal with a dark theme, and it should organize LeetCode problems by topic like arrays, strings, graphs, dynamic programming, trees, and so on.

The main thing is that I should be able to open the page, browse topic wise questions, mark each one as solved and revised, and quickly see my overall progress update in real time with stats and a progress bar. Please add a search box so I can find questions fast, and filters so I can view easy, medium, hard, solved, and unsolved problems.

Keep it lightweight and easy to use, just a straightforward web app with HTML, CSS, and JavaScript. I want it to feel like a practical study tracker, not a flashy product. If anything is unclear, look up current LeetCode style tracker examples online and make sensible choices.
