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.

Axe violations axe-core 4.13.0, full rule set

0 violating nodes across 0 rules, 382 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 1 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.

  • label-content-name-mismatch — Elements with visible text labels do not have matching accessible names. 6 nodes

Hygiene

Changes rarely — which is exactly why a change is worth noticing.
