/* ============================================================================
   NORTH STAR AUTONOMOUS — the design system, issue #51 (2026-09-17).

   "Autonomous industrial intelligence": pearl and titanium in the light,
   carbon and gunmetal in the dark, graphite type, one cyan signal, amber
   only where attention is owed. Composition by type, scale, hairlines and
   layered planes — not by rounded cards.

   The full constitution is docs/NORTH-STAR-AUTONOMOUS-WEBSITE-DESIGN-SYSTEM-
   2026-09-17.md in the Command Center repository. This file is its
   implementation: tokens first, then materials, then components, then the
   scenes, then print.
