Research direction

Start with the linked reproduction at quarto-accessibility-reprex, specifically post/post-1, and inspect the category filter links matching the reported selector above the post body. Verify the affected links against the axe color-contrast rule and confirm that their contrast reaches the WCAG AA 4.5:1 requirement under the default Cosmo-ish theme.
