MisterBooo/LeetCodeAnimation ? reverse-engineered prompt

Build me a clean website for learning LeetCode with animations, so people can actually see how each solution works instead of just reading code.

I want a homepage that lets users browse problems by number or topic, search for a specific problem, and open a problem page with an animation, a short explanation, and code examples in Python, C++, and Java. The animation view should feel like a teaching tool, with controls to play, pause, step through one move at a time, go back, change speed, and listen to voice narration. Make it easy to understand things like pointer movement, recursion, dynamic programming state changes, and graph traversal.

If you need current docs or examples, look them up online first. Keep the design simple and friendly, and make sure the content can be updated later from structured data so new problems can be added without rebuilding everything by hand.
