Axe violations axe-core 4.13.0, full rule set

11 violating nodes across 1 rule, 574 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 1 of 14 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.
