   Zapf Humanist 601 is Bitstream's cut of Optima (a humanist
   sans). Optima ships on every Apple/iOS device, so the stack
   below already renders the intended look on most phones.
   To serve the licensed Zapf Humanist webfont everywhere, drop
   the files into /assets/fonts/ (see assets/fonts/README.md) —
   this @font-face will pick them up automatically.
