   Inter is the variable font, which is why the stylesheet can use intermediate
   weights like 520 and 640 — static instances would snap those to the nearest
   of 400/500/600/700. Newsreader is a static instance: it is only ever used at
   400 italic for pull quotes, and the variable file cost 39KB more for range we
   never touch. Latin and latin-ext subsets only.

   Inter and Newsreader are licensed under the SIL Open Font License 1.1,
   which permits redistribution. See assets/fonts/OFL.txt.
