1Kết luận định lượng (held-out 200 ca)

Model	Kiểu train	Params	Epochs	Held-out Dice
STU-Net-S (transfer)	pretrained	14.6M	40	0.9585 🏆
nnU-Net (scratch)	from scratch	~30M	604	0.9549

STU-Net-S thắng ở mọi trục: Dice held-out cao hơn (0.9585 vs 0.9549, khác biệt có ý nghĩa TK — Wilcoxon p=0.015), đồng thời 2× ít param, 15× ít epoch, nhanh hơn/epoch. Đồng thuận giữa 2 model rất cao (Dice nnU↔STU ~0.977).
