/* A year in ten chapters, told on the game's own map: missiles over the
   Arctic, a war in Korea, then the politics that end both. Flat colours only:
   ink and paper, ember for war, laurel for peace, the game's own blue for what
   you hold. Detail comes from rules, hatching, stamps and paper, never fades. */
