   BANDGO IELTS — Hệ thống luyện thi IELTS cam kết band (7 cơ sở Hà Nội & Bắc Ninh)
   Phong cách: CORPORATE GIÁO DỤC PHỔ THÔNG, năng lượng "bứt phá band" (kiểu
   LangGo): header navy đậm chữ trắng, hero gradient navy, section xen kẽ trắng /
   xanh nhạt, nhiều số liệu và nút kêu gọi hành động màu đỏ cam.
   Màu: brand đỏ #D72229 (đậm #B01B21, nhạt #FFD2D2) theo tông LangGo, CTA cam #F28C0F, vàng #FAA61A (nút
   chính, nhãn giảm giá), vàng #F5B301 (ngôi sao, band điểm), nền trắng xen
   #F2F6FD, chữ #10203F, xanh lá check #1E9E63.
   Font: 'Montserrat' 800 cho tiêu đề, 'Inter' cho thân chữ (đều có Vietnamese).
   Điểm nhận diện riêng:
   (1) "Khối khóa học dạng banner ngang" (.cb): mỗi khóa là một dải 2 cột —
       trái: tên khóa to + 4 ô thông số (đầu vào / thời lượng / sĩ số / giáo
       viên); phải: ảnh bo góc có nhãn đỏ xéo góc "Giảm tới 12.000.000đ" —
       xen kẽ trái/phải theo thứ tự.
   (2) "Đồng hồ band" (.dial): vòng tròn tiến trình SVG (stroke-dasharray) hiển
       thị band 7.0+ / tỷ lệ 89,6% ở hero và bảng vàng.
   (3) Thanh CTA dính đáy trên mobile (.mcta) với 2 nút: Gọi hotline + Test miễn phí.
   Ảnh: link trực tiếp (images.txt) qua biến --img trên .ph; giáo viên / học viên
   dùng avatar chữ cái; chứng chỉ IELTS là thẻ CSS giả lập (.cert).
