/* ============================================================
   CSS RIÊNG CỦA TỪNG TRANG / CONTROL (gom từ các khối <style> trong .aspx/.ascx — skill khaithac-inline-styles)
   Quy ước: KHÔNG viết <style> hay style="..." trong trang; quy tắc riêng của trang đặt ở đây, bắt đầu bằng
   :where(.pg-<tên-trang>) — lớp do master gắn lên <body> (đường dẫn trang, bỏ đuôi .aspx, "/" -> "-", chữ thường;
   trang độc lập ghi sẵn trên <body>). :where() có độ ưu tiên 0 nên quy tắc giữ nguyên độ ưu tiên như khi còn ở trang.
   Control không trang nào dùng: bọc trong <div class="uc-<tên>">.
   Vị trí nạp = vị trí phHeader cũ: phHeader trong <head> -> ngay trước phHeader; phHeader trong <body> -> cuối <head>.
   Đường dẫn url() tương đối theo assets/css/ (../../ = gốc website).
