THOÁT NƯỚC THÁI NGUYÊN — Design system (tiền tố tn-*)
Phong cách: "Hạ tầng xanh" — cơ quan kỹ thuật đô thị: xanh dương đậm (nước, kỹ thuật),
điểm nhấn xanh lá (cây, núi — theo logo) và cam mũ bảo hộ cho hành động chính.
Góc bo vuông vắn (6–12px), vạch "đường ống" làm điểm nhấn, sóng nước ở chân khối.
