distinguish between Twing docs and content copied from Twig docs

Congrats on v1! 🎉

I just took a quick look at the docs. It's interesting that almost all of it is copied from Twig. As a user, it makes it hard to eyeball what Twig is, and what's unique about it (you've said you want to support things that aren't in Twig). Personally, it discourages me from reading — I would need to read along with the Twig docs in second window.

I wonder if there's a way to stick with your decision to not simply link the Twig docs, but also call out the parts of the documentation that are really Twing documenation— maybe distinct fonts, or coloring, or text highlights, or "twing!" badges in the margin?
