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
110 violating nodes across 4 rules, 2641 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 90 nodes -
serious
scrollable-region-focusable— Scrollable region must have keyboard access 16 nodes -
minor
empty-heading— Headings should not be empty 3 nodes -
moderate
landmark-one-main— Document should have one main landmark 1 node
Accessibility failures 2 of 29 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.
-
target-size— Touch targets do not have sufficient size or spacing. 98 nodes -
landmark-one-main— Document does not have a main landmark. 1 node
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
