     - Hero LƯỚI BENTO: 5 ô ảnh lệch cỡ, chữ khổng lồ nằm đè lên một ô
     - Lookbook MASONRY 3 cột (CSS columns), số thứ tự lớn
     - Sản phẩm: lưới 4 cột, hover đổi ảnh, giá nhỏ, nút chỉ hiện khi hover
     - Trang bộ sưu tập: ảnh xen chữ kiểu tạp chí, tiêu đề dọc
     - Chi tiết sản phẩm: ảnh cuộn dọc bên trái, thông tin sticky bên phải
