Nicely done. Pico.css is a cool idea I hadn't seen before.

I have built 2 SSG's over the years, once in 2009 and one this year. So it's fun to read through someone's internal thought process on their motivations and decisions.

Someone put together this mega list of 460 SSGs that I found helpful for inspiration and learning: https://staticsitegenerators.net/. Also would be a good place to add Teeny, though not sure if they are still updating the actual website.
