+ONNX model weights re-hosted for the **DepthField Photo** desktop app, which
+downloads them at runtime. All files here are **Apache-2.0** and are
+**redistributed unmodified** from their original sources. This repo is a stable
+mirror so the app fetches from a source we control; integrity is pinned by
+sha256 in the app's manifest.
