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

3 violating nodes across 2 rules, 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 2 nodes
  • serious color-contrast — Elements must meet minimum color contrast ratio thresholds 1 node

Accessibility failures 1 of 23 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 2 nodes

Hygiene

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