leachim6/hello-world ? reverse-engineered prompt

Build me a simple website that showcases a giant collection of Hello World examples in tons of programming languages.

I want it to feel easy to browse, with an alphabetical index, a search box, and pages or sections for each language that show the example code clearly. Keep it lightweight and practical, since this project is basically a living catalog that keeps growing. If you need to look up current docs or best practices for the stack, go ahead.

Please make the experience friendly for someone just exploring, so they can quickly find a language, open it, and see the Hello World snippet without confusion. Also include a clear note about how people can contribute new languages, since this repo is meant to expand over time.
