  Design system — hướng "Dark Luxury / Premium Gaming" cho Ngọc Rồng Online.
  Nền sâu gần đen, một accent cam-vàng "năng lượng" (khí công), glow tinh tế,
  bề mặt glass. Toàn bộ token gom về đây làm NGUỒN CHÂN LÝ DUY NHẤT — mọi trang
  tái sử dụng cùng biến thay vì tự chế màu. Cấp cả 2 cách đặt tên token
  (bộ mới --color-primary/--color-text-primary... và bộ cũ --color-accent/--color-bg...)
  để không trang nào bị vỡ khi đổi theme.
