/* =============================================================
   site-chrome.css — CSS dùng chung cho HEADER + FOOTER mọi trang.
   Nạp toàn cục trong includes/header.php (sau page CSS, trước
   theme/theme-style.php). Trước đây các rule này bị copy-paste vào
   từng file assets/css/pages/*.css với breakpoint lệch nhau khiến
   header/footer mỗi trang một kiểu (nhất là mobile). Bản chuẩn lấy
   từ style.css (trang chủ). theme/theme-style.php vẫn override để xử
   lý header-style (data-hd/ht/hm) và drawer mobile (.m4-*).
