/* bu-on.org — Ελληνικός οδηγός καζίνο.

   Editorial, not casino-dark: warm paper ground, Aegean blue for structure, terracotta for the one
   thing that must stand out. The fleet's gambling lands are dark with a neon accent; a guide whose
   whole argument is "check the regulator, not the banner" should not look like the banners. Every
   colour below is a token, so recolouring is eight lines, not a find-and-replace. */
