/* The Waiting Trade: site tĩnh 3 trang (chủ, privacy, terms). Cùng hệ màu với bộ nhận diện kênh (brand/brand-assets.html):
   nền đen, chữ trắng ngà, một điểm vàng duy nhất là chấm chạm mức. Không font ngoài, không script, không cookie:
   trang Privacy hứa đúng điều đó, thêm thứ gì gọi bên thứ ba thì phải sửa trang Privacy cùng lúc. */
