   VINUT GIAO VIỆC — UI KIT  (vinut-ui.css)
   Bộ giao diện cho hệ thống giao việc kiểu Redmine, nhận diện Vinut.
   Layout: thanh trên trắng + thanh bên xanh đậm thương hiệu, nội dung
   dạng bảng dữ liệu dày; đỏ Vinut chỉ dùng điểm nhấn (quá hạn, khẩn,
   đường cong logo dưới tiêu đề).
   Quy ước: mọi màu lấy từ token; class tiền tố ngắn, không phụ thuộc
   Bootstrap (có thể dùng song song Bootstrap JS cho modal/dropdown).
