What LCP is made of
A flat LCP number tells you something regressed. The subparts tell you whether it was the server, resource discovery, the download, or rendering.

Main thread work
Axe violations axe-core 4.13.0, full rule set
2 violating nodes across 2 rules, 5557 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
aria-prohibited-attr— Elements must only use permitted ARIA attributes 1 node -
serious
color-contrast— Elements must meet minimum color contrast ratio thresholds 1 node
Accessibility failures 2 of 20 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.
-
aria-prohibited-attr— Elements use prohibited ARIA attributes 1 node -
color-contrast— Background and foreground colors do not have a sufficient contrast ratio. 1 node
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
