/* The app's and auth's JetBrains Mono: the master, then the Latin subset as
   one family. The subset's range is the README's pyftsubset --unicodes list.
   The master's is the rest of Unicode plus the combining marks U+0300-036F,
   where it keeps all of its marks, so a sequence such as и + U+0301 renders
   whole from the master. Browsers try the last-declared face first. Latin
   text without combining marks never fetches the master: Chromium also
   fetches a face covering text while an earlier one is still loading. */
