Cascade layers - Learn web development | MDN
If you understood most of this article, then well done ā€” you're now familiar with the fundamental mechanics of CSS cascade layers. Next up, we'll look at selectors in detail.

I have no idea where Kevin learned about cascade layers, probably not this article though, cause it was first committed to their github this year... MDN has a lot of good info, and it's almost always correct. Not really sure what you mean by "too complex to find on mdn" though

you can have as much as layers you want and name them what ever you want. Kevin knows about the feature because he stays up to date with what ever is going on with css and what will be added in future specs.
