Start from the userscript included in the issue and inspect the current GitHub contribution calendar markup against its `ContributionCalendar-day` selector and `data-count`/`data-level` attributes. Update the selector or attribute references as needed, then install or run the script in GitHub and verify that contribution cells receive the intended fill colors.
