   Trang chi tiết sản phẩm (HomeNfcShop/ProductDetail) - thiết kế lại, dùng
   chung 1 file cho cả PC lẫn mobile (nạp qua @section styles ở cả 2 layout).
   Cùng ngôn ngữ thiết kế với trang Shop cá nhân (shopMember.css): tông teal,
   thẻ bo góc mềm, shadow nhẹ. Không đụng .product-item / _ItemProductPc2 -
   sản phẩm liên quan phải giữ nguyên style như trang chủ.
