 * HAS green academy house style. The values below are the official tokens from
 * https://www.has.nl (dist/assets/style-*.css), not approximations:
 *
 *   --has-green      #1cd354   brand primary
 *   --has-green-dark #274232   brand dark; the HAS header colour
 *   --has-ink        #14221a   near-black
 *   --has-magenta    #ea1fb6   brand B
 *   --has-blue       #008aff   brand C
 *   --has-error      #ec3b00
 *
 * Type: HK Grotesk for everything, Rois for h1/h2 — the same two-font split
 * the HAS site uses. Neither is bundled here; both degrade to the documented
 * fallback stack rather than to Times.
 *
 * Measured contrast, because the brand green is a trap on white:
 *   #1cd354 on #ffffff  2.00:1  FAILS AA  -> never used for text on white
 *   #1cd354 on #274232  5.49:1  passes AA  -> the accent role
 *   #274232 on #ffffff 10.99:1  passes AA  -> links, primary button
 *   #14221a on #ffffff 16.49:1  passes AA  -> body text
 * Every foreground/background pair used below is one of these.
