# Harbor requires Python >= 3.12 while openenv-base ships 3.11, so `uv sync` downloads its own
# interpreter and the venv's bin/python becomes a symlink into uv's install dir. Pinning that dir
# (and creating it up front, so the COPY below cannot fail when uv reuses a system interpreter)
# is what lets the runtime stage carry the interpreter the venv actually points at. Without it the
# venv arrives with a dangling bin/python and the container dies with "not found".
