/* kastor site.
   Monsoon (monsooncss@0.2.0) provides the base, utilities and the components
   used here (buttons, kbd, modal, command palette, accordion, breadcrumbs).
   This file adds the look: near black and white surfaces, hairline borders,
   faint grid lines, soft radial light and one amber to copper accent taken
   from the cut ends of the logs in the kastor mark. */
