/*
 * The board as a physical object.

 * `.game-board` is the printed panel: a dark rail around the edge, a double
 * brass rule printed just inside it, brass corner fittings, the city map
 * visible through a veil, and a paper grain over everything.
 *
 * `.board-zone` is an area printed onto that panel. Zones are recessed (see
 * `--well`) so pieces placed in them read as sitting above the surface.
