# Run the unit suite inside the actual container image, not against a bare Python
# on the runner — the image is the artifact we ship, so it's the thing we test.
# tests/ is excluded from the image by .dockerignore, so we mount it read-only
# into the built image and run unittest from /app (where the modules live).
