Main thread work
Axe violations axe-core 4.13.0, full rule set
1 violating node across 1 rule, 75 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.
-
critical
meta-refresh— Delayed refresh under 20 hours must not be used 1 node
Accessibility failures 2 of 31 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. 5 nodes -
label-content-name-mismatch— Elements with visible text labels do not have matching accessible names. 1 node
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
