/* Isthmus Meridian — Typography tokens
   ================================================================
   One family — Helvetica — carries the whole system. Weight and
   size do the work; the tone is clinical, spacious, confident.
   Big display words/numerals often use a light weight with a
   chrome/gradient fill (var(--grad-chrome)); body is regular.
