Build me a clean, easy to browse website for this C++11 to C++23 cheatsheet.

I want the content from the existing markdown files turned into a polished reference site with a simple homepage and separate sections for each C++ version. Make it easy to jump between language features and library features, and let people quickly scan examples and descriptions without having to dig through raw markdown.

Please keep the design lightweight, readable, and developer friendly, with good typography, clear headings, and a navigation that works well on mobile too. If it makes sense, add a search or filter so someone can find a feature fast, like optional, concepts, or coroutines.

Use the existing README and version files as the source of truth, and preserve the example code blocks and wording as much as possible. Look up current docs online if you need to, but keep the result focused on being a practical cheat sheet people can actually use.
