   Recharge & Event Planner — design tokens
   Concept: a late-night ops console for a spin-based recharge
   operation. Near-black surfaces, a single amber "Lucky" accent
   standing in for the gold wheel segments, monospace for every
   number that represents UC/dates so the ledger reads like a log.
