/* ============================================================================
   Popup "Hướng dẫn chọn size" cho trang landing tự chứa
   (vd: /giay-chan-bet-xixa-y1207) — nơi KHÔNG nạp /css/styles.css.

   Mọi quy tắc .size-guide-*, .sg-*, .xsf-* dưới đây được rút thẳng từ
   styles.css để popup ở landing giống hệt popup ở trang chi tiết sản phẩm.
   Kèm theo font, biến màu và reset — nhưng đóng khung trong .size-guide-drawer
   / .size-guide-overlay để không đụng tới giao diện landing.

   Tệp này SINH RA TỰ ĐỘNG: sửa popup ở styles.css rồi chạy lại
   scripts/gen-size-guide-css.py, đừng sửa tay ở đây.
