/* TÚI NGÂM CHÂN GIỮ NHIỆT — BẢN V2 (CRO, 24/09/2026)
   Khác bản gốc: chữ to hơn cho người lớn tuổi (thân 16px, chữ phụ ≥ 13,5px, xám đậm hơn), màn đầu = tiêu đề nỗi đau + video + giá + nút,
   khối giá nền sáng để nút đỏ nổi bật, đánh giá & chi tiết vuốt ngang cho trang ngắn lại, bỏ nút gọi nổi (gộp vào thanh đáy). */
