   GymBro — Design tokens
   Direction: "Iron & Chalk" — a dark, gym-floor palette. Charcoal like
   rubber flooring, chalk-white type, one signal accent (plate-collar
   orange) reserved for PRs, streaks and primary actions. Numbers are set
   in a mono face, like a plate's stamped weight — reps and sets are data,
   not decoration.
