   Cairo (SIL OFL 1.1) is self-hosted from assets/fonts/ as a VARIABLE font:
   one file per unicode subset covers the whole 400–800 weight range, so the
   Arabic reader downloads ~30KB instead of five static weights.
   The unicode-range split means Latin subsets are only fetched if the page
   actually contains Latin text. See assets/fonts/README.txt.
