  COLO PRO FONT:
  Colo Pro is a commercial font — to use it on the web you need the .woff2
  and .woff files (check your license allows web embedding, or purchase a
  web license from the foundry). Once you have them:
  1. Drop the files into assets/fonts/
  2. Update the src paths below
  3. Reload — it will work automatically
  Until then, Nunito (loaded from Google Fonts) is the fallback.
