/* Fog Line: the field, the reefs, the tokens, the fight card. A plotting
   table seen from above in the theme's ground, with a bank of fog across
   the middle rows: not a board from any box, no plastic stands, no flags
   on pegs. Shared HUD pieces are in hud.css.

   Colour is never the only cue: a unit is its glyph (and its number), a
   side is its insignia, a reef is hatched rock, a cell a unit can step to
   carries a dot, one it can attack a crosshair ring, and the unit picked a
   white frame. */
