   Sương Homestay — style.css
   Phong cách: ấm áp, gần gũi, kiểu "tạp chí nhà" (cozy editorial).
   Màu: trắng sương #F6F4EF + rêu #4F6B4A + thông đậm #22362A + đất nung #C9683C,
   chữ xám ấm. Font: "Fraunces" (serif mềm, nhấn nghiêng) + "Nunito".
   Bố cục khác các mẫu trước:
     - Header tối giản: logo TRÁI, phải CHỈ có "Phòng" + nút "Đặt phòng";
       các link còn lại nằm ở THANH PHỤ MỎNG DÍNH dưới hero (.subnav) và
       tự sáng mục đang xem khi cuộn (JS)
     - Hero KHÔNG tràn viền: tít serif lớn bên trái (chữ nghiêng màu đất nung),
       bên phải CHỒNG 3 ẢNH POLAROID xoay lệch có chú thích; nhãn "Còn 2 phòng"
     - THANH ĐẶT PHÒNG nổi đè mép dưới hero (ngày đến / ngày đi / khách / Xem giá)
     - Phòng: HÀNG LỚN XEN KẼ ảnh 60% / thông tin 40%, có dải 7 ô ngày còn trống
     - "Một ngày ở Sương": nhật ký DỌC có mốc giờ bên trái, ảnh bên phải (.diary)
     - Bếp & bữa sáng: 3 thẻ món có danh sách thực đơn chấm chấm
     - Quanh nhà: danh sách kiểu bản đồ, chip khoảng cách / đi bộ / xe máy
     - Chuyện nhà: vòng tròn chữ cái đầu chủ nhà + trích dẫn dài + 3 nội quy
     - Nhận xét: masonry giấy note có ghim, xoay nhẹ
     - Footer đơn giản 2 cột
   Ảnh: mỗi khối ảnh dùng biến --img trên thẻ HTML (đường dẫn ../images/…).
