   Hệ chữ và màu lấy TRỰC TIẾP từ CSS đang chạy trên apple.com/vn
   (main.built.css + homepage.built.css, tải về 14/09), đối chiếu với
   design-md/apple/DESIGN.md — VoltAgent/awesome-design-md.

   Chữ phụ: #6e6e73 trên nền sáng · #86868b trên nền tối · nền tối là #000 thật
   Ô sản phẩm: padding 48px 0 56px, nội dung xếp cột và căn giữa

   LƯU Ý cách Apple đặt chữ: TÊN SẢN PHẨM là dòng tiêu đề khổng lồ
   (<h2 class="tile-headline">iPhone 18 Pro</h2>), câu quảng cáo chỉ là dòng phụ.
   Trang này làm đúng vậy: "Effects Live Pro" là dòng to nhất.

   Màu nhấn: XANH APPLE, không đổi sang màu khác. Đúng một màu cho mọi thứ
   bấm được — nút, liên kết, viền chọn — theo luật "chỉ một màu nhấn".
