  # Force version overrides across every `uv pip install` in this workflow via UV_OVERRIDE:
  #   - tokenizers<0.23.0, even when transformers@main declares a higher lower-bound.
  #   - torch/torchvision/torchaudio pinned to the image's baked-in set so `-U` installs
  #     (e.g. accelerate@main) can't bump torch and break torchvision's C++ ABI
  #     (torchvision::nms). The pinned set is (re)written into the override file per job below.
