/* ============================================================================
   BOARDS -- the drawing layer for `ui/kit.js` and the per-game renderers.
   ==========================================================================

   Loaded on TOP of whichever page stylesheet is in play, so it uses that
   page's variables (--bg, --panel, --line, --ink, --dim, --accent) and never
   redefines them. The arena and the study build look different on purpose and
   the boards should inherit that difference rather than override it.

   ON COLOUR. Four seat hues exist and NONE of them carries meaning on its
   own: every coloured mark in the kit is drawn with the seat's name beside
   it, and `KIT.actions` gives every option in a row the same class. A reader
   who cannot separate the blue from the violet loses nothing but decoration.
   The one place colour is load-bearing is a fill's LENGTH, which is a
   position, not a hue.
