+# NOTE: `wifi-densepose-nn` was declared here but never imported anywhere in
+# this crate's src/ or bin/ (the tch-backend model path uses `tch` directly,
+# not this crate). It was a dead dependency that pulled `ort` (ONNX Runtime) +
+# reqwest/hyper into every downstream consumer — including the ADR-185
+# `[meridian]` wheel. Removed to slim the dependency graph. Inference at
+# serving time is done via `wifi-densepose-nn` by the binaries that actually
+# load models, which depend on it directly.
