It's easy, eventually
I've been looking at Eleventy for a while now,
git cloned and fiddled with a few different beginner repos. It's only just starting to make sense, now that I've committed to using it for the 2020 blog.
(A big weird thing I'm looking forward to figuring out: how to keep the '18-'19 blog up, alongside 2020, which I intend to keep in a new way-less-asset-heavy repo.)
