+# matrix picks one per job; dependencies are pre-installed into each, so a CI

+# without --break-system-packages, and keeps the four dependency sets isolated.
+#
+# The package list is written once so versions cannot drift between
+# interpreters. It mirrors pyproject.toml's runtime deps plus the test and dev
+# extras; keep the two in step.
+#
+# Deliberately NOT installed: pyWebLayout itself. The workflow installs the
+# checkout with --no-deps, so a job always tests the code under review.
+#
+# setuptools is pinned below 81 because that release dropped pkg_resources,
+# which coverage-badge still imports at startup. Without the pin the badge step
+# dies with ModuleNotFoundError. Revisit when coverage-badge stops using it.
