/* The palette, once. Written 1 Oct 2026 (the final polish pass), when the
 * same twenty-odd tokens had been copied into the :root of twenty-seven
 * screens and had quietly drifted: two reds both called --brick, five values
 * of --faint, four ambers, and a house stylesheet repeating every value as a
 * fallback because it loaded last and could not declare them.
 *
 * Linked FIRST on every screen, before the screen's own <style>, so a screen
 * can still override a token on purpose (and says why, in a comment beside
 * the override). hub-house.css loads last and carries no fallbacks: a var()
 * here always resolves. The pill, mark and tone tokens stay in hub-house.css
 * because they are rules about meaning, not colours.
 *
 * NOT the printed documents. Those are Cambridge-facing and keep their own
 * header colours (Ramy, 23 Sep 2026: "leave the printed documents alone"). */
