/* ===== THEME OVERRIDE =====
 * Đổi màu nhận diện cho từng thư viện: bỏ comment và chỉnh các biến dưới đây.
 * Chỉ đổi accent - KHÔNG đổi các màu trạng thái (--ok/--warn/--danger/--info).
 *
 * Gợi ý bảng màu theo chủ đề:
 *   Xanh dương  #2b6cb0/#1a365d  (mặc định - đấu thầu, hành chính)
 *   Xanh teal   #0d9488/#134e4a  (CNTT, công nghệ)
 *   Xanh lá     #2f855a/#1c4532  (môi trường, nông nghiệp)
 *   Tím         #6b46c1/#44337a  (giáo dục, văn hóa)
 *   Nâu đất     #975a16/#5f370e  (đất đai, xây dựng)
 *   Đỏ gạch     #c05621/#7b341e  (y tế, lao động)
