# GitHub Actions Workflow: Build opencv-python with CUDA support on Windows
2+
#
3+
# This workflow compiles opencv-python from source with CUDA enabled on a
4+
# GitHub-hosted Windows runner. The resulting Python wheel is then uploaded
5+
# as a build artifact.
6+
#
7+
# This is a complex and long-running process. It is configured to run only
8+
# on manual trigger (workflow_dispatch).
