/* ==========================================================================
   RICHGAME Co., Ltd. — shared stylesheet
   Concept: "faceted gem" — the brand sits at the intersection of RICH (gems,
   value, gold) and GAME (points, levels, motion). Every angled cut in this
   file is a facet, echoing a cut gemstone; gold marks value, emerald marks
   the game/tech layer underneath it.
