/* Tablut board: a 9x9 float-grid (same technique as hnefatafl above -
   note the explicit width override below, since the shared .square
   base class hardcodes 12.5% for an 8-column board). Sides are told
   apart structurally, not by color alone: attackers are a filled
   disc, defenders an outlined disc, and the king gets his own crown
   marker on top of a defender disc - the same convention used for
   the smaller Brandub board. */
