/* Forget Nothing Board — Legends of the Game
 *
 * Colour lives entirely in custom properties on :root. The dark set is
 * redefined twice on purpose: once behind prefers-color-scheme for a visitor
 * who has never touched the toggle, and once behind [data-theme] so the
 * toggle wins in both directions. Never style a component inside one of
 * those blocks — take the token instead, or the page renders one theme's
 * text on the other theme's ground.
