A display sink that overlays bounding boxes and text on an image input and shows it in an OpenCV window. Based on opencv-plot from dora-hub, brought up to the dora 1.0 node contract and packaged with uv. Python rather than Rust: the opencv Rust crate generates its bindings from the OpenCV headers on the build machine, so it needs libopencv-dev and libclang-dev per machine and per architecture and does not cross-compile. Every dependency here ships prebuilt wheels for linux-x86_64, linux-aarch64 and macos-arm64. Covers every encoding the upstream node did — bgr8, rgb8, jpeg/jpg/jpe/bmp/ webp/png, yuv420 and avif — plus both bbox formats, the text overlay, PLOT_WIDTH/PLOT_HEIGHT and headless operation under CI=true.

# Two gates, neither of which needs a camera or a display: the dataflow still

# matches the typed contract in dora-node.yml, and the node's own tests pass.
