U2Net only ever downloaded lazily on the first Remove Background click, unlike SAM which retries on every container start. If that one attempt failed (DNS/firewall) the model was never fetched again, surfacing as "No background removal method available. Install u2net or rembg." Mirrors the existing SAM auto-download/AUTO_DOWNLOAD_SAM pattern for U2Net, and documents manual host-side recovery in the README. Also deletes backend/app/services/u2net_model.py (hand-written U2NET/U2NETP PyTorch classes) — unused since tools.py switched to cv2.dnn.readNetFromONNX for background removal.
