   Spa Ngọc Lan — style.css
   Phong cách: tối giản, nhiều khoảng trắng (soft minimal). Nền ngà,
   xanh sage + hồng đất, chữ mảnh, bo góc lớn.
   Bố cục khác các mẫu trước:
     - SIDEBAR DỌC cố định bên trái (logo, menu, liên hệ), nội dung cuộn bên phải
     - Hero CHIA ĐÔI: chữ một nửa, ảnh một nửa tràn mép
     - Dịch vụ xếp ZIG-ZAG ảnh/chữ xen kẽ
     - BẢNG GÓI GIÁ 3 cột, gói giữa nổi
     - So sánh trước/sau bằng thanh kéo
   Ảnh: mỗi khối ảnh dùng biến --img trên thẻ HTML (đường dẫn ../images/…).
