seanprashad/leetcode-patterns ? reverse-engineered prompt

Build me a clean study site for LeetCode interview prep that organizes problems by pattern instead of just dumping a random list of questions.

I want it to feel like a guided practice hub where someone can browse fundamentals, read short notes on common data structures and algorithms, and then explore a question list grouped by topic. Make the list easy to scan and filter, since this project uses a table style layout. Include a simple way to open each problem, see whether it is premium, and jump to related solutions or notes when available.

Keep the design modern and readable, with a light and dark logo, a strong focus on content, and a polished learning experience. If you need current implementation details, look up the latest docs online first.
