# Replace PyPI opencv wheels (which bundle vulnerable ffmpeg 5.1.x with 14 CVEs)
# with a source-built opencv-contrib-python-headless wheel compiled with
# WITH_FFMPEG=OFF + ENABLE_CONTRIB=1 + ENABLE_HEADLESS=1.
#
# The contrib-headless variant is a strict superset of the cv2 API exposed by
# opencv-python, opencv-python-headless, and opencv-contrib-python (all of
# which are pulled in transitively by unstructured-paddleocr / unstructured-
# inference). One wheel can therefore replace all three. Because the wheel's
# metadata name only matches opencv-contrib-python-headless, we have to
# uninstall the other variants first - `uv pip install --reinstall-package`
# would silently no-op for the non-matching names.
#
# See: https://github.com/opencv/opencv-python/issues/1212
#
# Note: uv.lock resolves opencv packages to 4.13.0.92, but our wheel is pinned
# to 4.12.0.88 because 4.13.0.92 has no sdist on PyPI — our GHA workflow
# (build-opencv-wheels.yml) compiles from source and requires an sdist.
# Bump this when a newer version publishes an sdist.
