/* ==========================================================================
   Kzyx Solutions — design system
   Canonical tokens (consumed by the portal too — do not rename):
   --kz-accent, --kz-accent-text, --kz-accent-hover, --kz-on-accent, --kz-bg,
   --kz-surface, --kz-surface-2, --kz-text, --kz-text-muted, --kz-border,
   --kz-radius, --kz-font-brand, --kz-font-mono

   --kz-accent is decorative (fills, borders, icons, focus rings; 3:1 non-text
   contrast is enough). --kz-accent-text is the AA-compliant variant for accent
   TEXT — always use it when the accent colors letters.

   in an ocean of empty space. Steps, not vw-fluid: predictable rendering at
