   Nền kem, tiêu đề serif, nhấn vàng đồng, thẻ tour có khối chữ đè lên ảnh,

   LƯU Ý CHỮ TIẾNG VIỆT: dấu chồng (Ồ, Ữ, Ệ) cao tới 1.15em ở chữ thường và
   1.24em ở chữ hoa. Mọi line-height tiêu đề tối thiểu 1.24 — đừng hạ xuống.
   Nhãn dùng chữ thường giãn nhẹ, không IN HOA: hoa tiếng Việt cao hơn 47%.
