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
14 violating nodes across 3 rules, 295 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 12 nodes -
moderate
landmark-one-main— Document should have one main landmark 1 node -
moderate
meta-viewport— Zooming and scaling must not be disabled 1 node
Accessibility failures 2 of 14 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.
-
meta-viewport— `[user-scalable="no"]` is used in the `<meta name="viewport">` element or the `[maximum-scale]` attribute is less than 5. 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.
