I’ll trace the xkcd fallback and the repository’s warning policy, then make the smallest behavior/test adjustment and rerun the exact render CI command.

The fallback warning is intentional and already has a dedicated test. The two failing tests exercise rc-context behavior, but they accidentally depend on whether the runner has a comic font installed. I’m isolating those tests from that environment-specific warning while preserving the warning contract itself.

The exact CI slice is now running. The change is test-local, so the library still warns when xkcd fonts are unavailable, and the dedicated fallback test still verifies that behavior.

The render suite passes. I also detected unrelated staged test changes appearing in the shared worktree during the run; I’m checking the final diff carefully so I report only this fix and do not disturb anyone else’s work.

Fixed the font-dependent failures by filtering the intentional xkcd fallback warning in the two rcParams tests: test_render_matplotlib_coverage.py.

Exact CI command now passes: 336 passed, 2 skipped.
