nilbuild/design-patterns-for-humans ? reverse-engineered prompt

Build me a simple, friendly website that teaches design patterns in the easiest way possible.

I want it to feel like a visual guide for beginners, with a clean landing page and easy navigation to each pattern. Start with a short intro explaining what design patterns are, then group them into creational, structural, and behavioral patterns. For each pattern, show a plain English explanation, a real world example, and a small code example. Keep the tone playful and non intimidating, like it is helping someone finally get it.

Make it look polished and readable on desktop and mobile, with a nice banner, clear headings, and a table of contents so people can jump around quickly. Use the existing content as the source of truth, and if you need to look up current docs or improve the examples a bit, feel free to do that. The main goal is to make the topic feel simple, visual, and easy to skim.
