ashishps1/awesome-low-level-design ? reverse-engineered prompt

Build me a clean learning site for low level design interview prep.

I want it to organize the material into easy sections like OOP basics, design principles, design patterns, UML, concurrency, and common interview problems. It should feel like a helpful study hub where someone can quickly jump to topics like Parking Lot, LRU Cache, ATM, Elevator, Tic Tac Toe, and other classic design questions, then open a page with the main idea, class diagram, key objects, and a simple Java example.

Please make the layout simple and readable, with a strong homepage, a sidebar or table of contents, and nice sections for beginners and interview practice. Use the existing diagrams and images where they make sense, and keep everything easy to scan. If you need current documentation or best practices for presentation, look them up online. I mostly want something polished that makes it easy to learn and revise without hunting around.
