   The single source of truth for the design

   styles.css and any page-local styles.

   Rules of use:
   - No page may define its own :root color,
     type, or spacing custom properties.
   - Tokens ending in -deep are the ONLY legal
     variants for text under 24px on light
     backgrounds (WCAG 2.1 AA).
   - --gold and --emerald are decorative /
     dark-background colors. Never body text
     on white.
