Axe violations axe-core 4.13.0, full rule set

23 violating nodes across 1 rule, 145 passing. This is a standalone axe run, stricter than the subset Lighthouse folds into its score above — and it is the second tiebreaker in the ranking.

  • serious color-contrast — Elements must meet minimum color contrast ratio thresholds 23 nodes

Accessibility failures 1 of 18 audits

Tracked as a count, not just the score — the weighted score is coarse enough that you can ship a broken component and barely move it.

  • color-contrast — Background and foreground colors do not have a sufficient contrast ratio. 23 nodes
