   Self-hosted rather than fetched from Google. The app's whole pitch is that
   it talks to nobody you didn't ask for, and a page making that argument while
   handing every visitor's IP to a font CDN undercuts it before they've read a
   word. These are the same families, variable, under the SIL Open Font
