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
17 violating nodes across 3 rules, 856 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
color-contrast— Elements must meet minimum color contrast ratio thresholds 12 nodes -
minor
image-redundant-alt— Alternative text of images should not be repeated as text 4 nodes -
serious
link-in-text-block— Links must be distinguishable without relying on color 1 node
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.
-
color-contrast— Background and foreground colors do not have a sufficient contrast ratio. 12 nodes -
link-in-text-block— Links rely on color to be distinguishable. 1 node
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
