# ipykernel and nbformat resolve jointly with the pins in one invocation so
# any conflict fails the build instead of silently changing a pinned version.
# ipywidgets is part of the kernel environment for the same reason it is on
# Colab: tqdm (and anything else that renders widgets) routes to ipywidgets
# inside Jupyter and raises "IProgress not found" without it.
# gcc/libc6-dev cover pins with no wheel for the target arch (e.g. old psutil
# on arm64) and are purged in the same layer to keep the image slim.
