/* Cairn design system.

   Light and editorial: large light-weight headlines (Lexend), small monospace
   labels (IBM Plex Mono), hairline borders instead of heavy shadows, soft
   pastel gradients, pill buttons with a round arrow badge, and a deep
   green-ink for dark bands. Fonts are self-hosted in web/fonts (SIL OFL);
   nothing loads from another site. Every text and background pair meets
   WCAG 2.2 AA in light and dark mode. */
