   0. Design tokens — "Cyber Neon"
   Chế độ TỐI là mặc định (:root). Primary = cyan (#22d3ee), Secondary = xanh
   dương (#3b82f6), Accent = lime (#a3e635). Nút chính dùng gradient
   cyan→xanh với chữ tối (--on-brand) để đạt tương phản cao.
   --brand/--brand-2/--accent/--device/--software được theme-config.php > colors
   ghi đè qua wp_add_inline_style() (xem functions.php).
   --navy/--navy-2/--on-navy là bề mặt "luôn tối" (header, footer, banner...)
   cố định ở cả 2 chế độ. --link là màu chữ liên kết/nhấn (tối hơn ở chế độ
   sáng để đủ tương phản trên nền trắng).
