# The repository's own example: a webcam and a fixed caption feeding the viewer.
# The plot node is built from this checkout with `path:` + `build:`, so
# `dora validate` picks up the typed contract in dora-node.yml next to it.
#
# Run it with `--uv` so every Python node gets its own managed environment.
# A consumer wires the node from a tag instead — see README.md.
#
# `bbox` is left unwired: every bbox source is a detector, and pulling one in
# would put a model download in the way of a webcam preview. README.md shows
# the wiring.
