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
41 violating nodes across 3 rules, 448 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.

Accessibility failures 3 of 26 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. 31 nodes -
listitem— List items (`<li>`) are not contained within `<ul>`, `<ol>` or `<menu>` parent elements. 3 nodes -
aria-required-children— Elements with an ARIA `[role]` that require children to contain a specific `[role]` are missing some or all of those required children. 1 node
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
