   Trang Chương trình ưu đãi — form "Đăng ký học lái xe tại Hiệp Phát" (09/11/2026)
   Thay hộp "Đăng ký để nhận ưu đãi" cũ: 1 form Đăng ký tư vấn (Họ tên, SĐT, Hạng đào tạo quan tâm).
   09/11: bỏ cột "Đăng ký nhập học" theo yêu cầu chủ dự án.
   Màu Design System Hiệp Phát: xanh #2b26fb · đỏ #ea1e24 · navy #2d3489 · chữ #0a1330.
   Chữ nội dung ≥ 17px, phụ ≥ 14px, ô nhập / nút ≥ 52px.
   Selector có "html body:is(.uu-dai-page, .has-uu-reg) .uu-reg" để thắng .tn-offer cũ trong style.css.
