Axe violations axe-core 4.13.0, full rule set

68 violating nodes across 2 rules, 518 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 67 nodes
  • moderate page-has-heading-one — Page should contain a level-one heading 1 node

Accessibility failures 1 of 13 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. 67 nodes

Hygiene

Changes rarely — which is exactly why a change is worth noticing.
