/* ==========================================================================
   Sổ tay nhiệm vụ — Văn phòng Tỉnh ủy Lào Cai
   Hệ thiết kế: trang trọng, rõ ràng, tương phản cao (phong cách "Accessible & Ethical").
   - Màu nhấn duy nhất: đỏ cờ; vàng sao chỉ dùng làm chi tiết (ngôi sao, vạch đánh dấu).
   - Điểm nhấn thị giác đặt ở thanh bên đỏ thẫm; vùng nội dung giữ yên tĩnh, nền trắng – xám lạnh.
   - Font Be Vietnam Pro (thiết kế cho tiếng Việt), lưu sẵn trong static/vendor/fonts — chạy không cần internet.
