   MarTech — design tokens
   Hệ màu "Circuit": nền tối gần đen cho các khối hero/CTA, đi kèm
   dải gradient tín hiệu (cyan → blue → violet → coral) làm chữ ký
   thị giác xuyên suốt — vibe công nghệ (cyan/blue) + marketing (violet/coral).

   Các biến màu bên dưới là giá trị MẶC ĐỊNH. Nếu theme-config.php đổi màu,
   functions.php sẽ in đè 1 khối :root{...} khác ngay sau file này (xem
   martech_inline_theme_vars() trong functions.php) — không cần sửa file này.
