   Two families: a geometric display face (wordmark + large
   moments) and Century Gothic for all copy. Both substituted
   by Jost here. Mono is reserved for part numbers / specs.

   Casing rule (brand book): Sentence case everywhere; ALL CAPS
   only for part numbers and standards. Italic is used on the
   live site to emphasize the key phrase in a headline.
