/*
 * assets/css/site-header.css
 * Trích & tái sử dụng NGUYÊN các rule #header-bar/#logo/#header-right/.btn-header/.user-* từ
 * assets/css/map.css (header trang chủ index.php) — CÙNG tên class/id, CÙNG màu/kích thước, để
 * header ở 15 trang public độc lập giống hệt header trang chủ. Chỉ khác duy nhất:
 *   - #header-bar dùng position:sticky thay vì absolute (index.php có bản đồ toàn màn hình nền
 *     dưới header nên header nổi đè lên; các trang này là trang nội dung thường, header phải đẩy
 *     nội dung xuống bằng flow bình thường + sticky khi cuộn).
 *   - Thêm .menu-parent-btn/.menu-dropdown cho menu cấp 2 (dropdown) — tính năng mới, trang chủ
 *     hiện chưa có vì trước đây chỉ có 2 nút cố định "Tin đăng"/"Đăng tin" không cần dropdown.
