Axe violations axe-core 4.13.0, full rule set

2 violating nodes across 2 rules, 344 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.

  • moderate landmark-banner-is-top-level — Banner landmark should not be contained in another landmark 1 node
  • moderate landmark-contentinfo-is-top-level — Contentinfo landmark should not be contained in another landmark 1 node
