/* =========================================================================
   Workout Tracker
   Design language: a gym is loud, bright-screen-glare, and used one-handed
   mid-set. Dark surface to cut glare, one hot "effort" accent (molten
   orange-red) for primary actions and stepper emphasis, and mandated
   green strictly reserved for a *completed* set -- so green always means
   "done" and never means anything else in this UI.
