# Runs the Python test suite and the checked-in artifact checks on every push
# to main and every pull request. The colour tools compare against the
# CIE 1931 2-degree CMF table, which is CC BY-SA 4.0 and not redistributed
# here: it is fetched at run time and rejected unless its SHA-256 matches the
# pin the tools themselves enforce.
