/* Design tokens — a control-room instrument panel, not a SaaS dashboard.
   System font stacks are deliberate here, not a fallback: this runs on a
   private VPN interface that may have no route to a font CDN, and a data
   console like this earns its personality from scale/weight/spacing and a
   restrained status palette rather than an imported display face. */
