   Fonts. Self-hosted variable fonts (SIL OFL, licences next to the files).
   Per family, a small "core" file with ASCII and the site's punctuation at
   the weights used here (preloaded), then Google Fonts' latin and latin-ext
   files for every other character: a browser downloads only the files a
   page has characters for. The block below is generated by subset-fonts.py.
   The version is in the file names because vendor/fonts/ is cached as
   immutable (_headers): replacing a font means a new name.
