/* claudebox design system.
   Idea: a machine's front panel. Ink-navy header/footer like a rack faceplate, sodium-amber as the
   single "lit" accent, status pills with LED dots. Type: Unbounded (display), Golos Text (text).
   Scale: 1.25 (major third) from 17px. Colors are tokens; dark theme via prefers-color-scheme. */
