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
18 violating nodes across 3 rules, 257 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
region— All page content should be contained by landmarks 10 nodes -
serious
color-contrast— Elements must meet minimum color contrast ratio thresholds 7 nodes -
serious
frame-title— Frames must have an accessible name 1 node
Accessibility failures 3 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.
-
color-contrast— Background and foreground colors do not have a sufficient contrast ratio. 8 nodes -
frame-title— `<frame>` or `<iframe>` elements do not have a title 1 node -
landmark-one-main— Document does not have a main landmark. 1 node
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
