Why every demo has to actually work

Early on I could have written this site as a set of articles explaining Eleventy patterns, with code snippets and screenshots. I didn’t, because I’ve read plenty of tutorials like that and forgotten them a week later.

So every demo here has a “Live Implementation” section that’s the real, working thing: the actual header search, the actual theme toggle, the actual multi-level nav. If a code snippet ever drifts from what’s really running, it’s a bug, not just an out-of-date doc. That’s a much better forcing function for keeping things honest.
