   Bố cục: hero xanh → thẻ thông tin gối lên hero → form (trái) + thẻ gọi nhanh / bản đồ (phải).
   Tên class là hợp đồng với Frontend/Contact.aspx và Contact.aspx.cs (RenderMap sinh .contact-map /
   .contact-map-link) — xem quy tắc 13 trong CLAUDE.md. Sửa file này xong phải tăng ?v=N ở Contact.aspx.
