/* Giao diện Liên đội — phong cách tạp chí tuổi học đường, phẳng và thoáng.
   Đỏ (#D32F2F) = màu chủ đạo: thanh điều hướng, tiêu đề, nút hành động. Vàng (#FBC02D) = viền nhấn, huy hiệu.
   Xanh lá (#2E7D32) = điểm xuyết cho phong trào xanh, kế hoạch nhỏ, góc sáng tạo. Nền trắng/xám rất nhạt, chữ xám than (#1F2937).
   Phông: Be Vietnam Pro. Bóng đổ chỉ một mức nhẹ: 0 4px 6px -1px rgba(0,0,0,.08). */
