@pimoore Thanks! Glad you like it :-). Looking at Google Fonts for a way to download .woff files, I just realised that I'm using EB Gramamond, not Baskerville, which is embarrassing! I did test with Baskerville, but the free version didn't have the right weights available, so I switched and forgot that I switched. I'll update the post. Anyway, I'll see if I can find .woff formats or convert from .ttf.
I haven't found the 100GB a month limit a problem at all. I don't have huge traffic, and I host the images (other than design assets) off site (on Backblaze B2) and link to them, but my bandwidth is usually 3-5GB per month, so I am nowhere near the limit. YMMV of course, depending on a variety of factors.
