/* =========================================================
   KRI guest sites - design tokens and component patterns

   Source: /root/src/kri-website/src/assets/style.css
           (KRI ry static site design system: slate + live KRI blue + paper)
   Read through its script-refreshed mirror in this repo,
   wp-content/mu-plugins/kri-booking-skin/assets/style.css (see refresh-css.sh).

   Values are copied from the source, not invented, and the source token
   and class names are kept. NOTE: the --amber-* tokens are BLUE. They are
   backwards-compatible aliases of --highlight-* (the KRI blue), not amber.
   This file does not load the Inter and Fraunces webfonts; the page does.
   The only section not lifted from the source is "Forms" at the end,
   which is marked DERIVED.
