/* Art Keeper website. Saffron Studio, with Art Keeper's terracotta accent.
 *
 * Every colour and font family is set in the custom properties at the top of
 * this file, so the look can be switched in a few lines:
 *   - Accent: change the five "Accent" tokens (light and dark blocks).
 *   - Headlines: change --font-display and --display-weight (see "Type").
 * Nothing below the tokens names a colour or a font directly.
 * Fonts are self-hosted (assets/fonts), so no third party sees visitors.
