/* ============================================================
   Cờ Cá Ngựa — Visual layout
   Fonts: Grenze (logo), Averia Serif Libre (headings), Poppins (body)
   The square size is set on #board-wrap by board.js as --cell and
   --horse, since it depends on how much room there is.

   The board is painted warm and bright, the way a real cá ngựa
   board is; the panel keeps the arcade's dark chrome so the game
   still belongs to the set.
