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

4 violating nodes across 1 rule, 228 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.

  • serious svg-img-alt — <svg> elements with an img or image role must have alternative text 4 nodes

Accessibility failures 1 of 24 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.

  • svg-img-alt — SVG elements with an `img` role do not have an accessible text alternative 4 nodes
