/* ═══════════════════════════════════════════════════════════════════════════
   Paddock — black and green, in the Game Room's house style.

   The BOARD is the interface, so the chrome stays quiet: one accent green for
   the field you have claimed, a dark green for open grass, blue for water and
   a warm timber for fences, so "what is mine" reads instantly.
