/* Norskpenn. The type is Atkinson Hyperlegible Next, drawn by the Braille
   Institute so that similar letters can't be confused: the right face for
   people reading and writing in a second language. Its zero is slashed,
   which in Norwegian reads as Ø, so we serve a copy with an open zero
   (scripts/open-zero.py) under the name Norskpenn Sans. The palette is a written
   page: cool white paper, ballpoint-blue ink for what you can do, and the
   teacher's red only for corrections, so red always means "fix this". */
