What LCP is made of observed, unthrottled
A flat LCP number tells you something regressed. The subparts tell you whether it was the server, resource discovery, the download, or rendering.
Measured on the trace before throttling is modelled, so these are real durations that will not sum to the 3.78 s above — that figure is a simulation of the same load on a slow phone and connection. Read these for the proportions: which phase dominates.

Axe violations axe-core 4.13.0, full rule set
27 violating nodes across 4 rules, 1493 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 18 nodes -
serious
color-contrast— Elements must meet minimum color contrast ratio thresholds 7 nodes -
serious
aria-input-field-name— ARIA input fields must have an accessible name 1 node -
critical
select-name— Select element must have an accessible name 1 node
Accessibility failures 5 of 31 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. 7 nodes -
label-content-name-mismatch— Elements with visible text labels do not have matching accessible names. 5 nodes -
aria-input-field-name— ARIA input fields do not have accessible names 1 node -
aria-prohibited-attr— Elements use prohibited ARIA attributes 1 node -
select-name— Select elements do not have associated label elements. 1 node
Hygiene
Changes rarely — which is exactly why a change is worth noticing.
