Axe violations axe-core 4.13.0, full rule set

0 violating nodes across 0 rules, 877 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.

Accessibility failures 2 of 22 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.

  • target-size — Touch targets do not have sufficient size or spacing. 28 nodes
  • button-name — Buttons do not have an accessible name 1 node
