   Quan hệ cổ đông — trang danh sách tài liệu (Báo cáo tài chính, Công bố
   thông tin, Báo cáo thường niên, Đại hội đồng cổ đông).

   Bố cục "report list" light-mode: hero đỏ + breadcrumb + lọc theo năm +
   danh sách thẻ báo cáo (tải PDF) + sidebar tin mới nhất.

   Mọi class prefix `qhcd-` để không đụng .hero/.pager/.news-item của theme.
   Token gói trong .qhcd-page để độc lập với biến toàn cục của theme.
