Metrics LAB

No field data: the Chrome UX Report is not being collected for this project, so every figure below is from the Lighthouse run.

Metric Lab Simulated
Value Change / range Trend
LCP CWV (estimate) Largest Contentful Paint 1.09 s good ↑ +25 ms (+2.3%) 1.07 s – 1.09 s
INP CWV Interaction to Next Paint — field only, no lab run can measure it n/a

LCP Subparts LAB Unthrottled

The subparts attribute LCP to your server, resource discovery, download, or rendering. Note that the Lab LCP shown above is a simulated throttled estimate.

The same load, photographed twice at 412×823: once with scripts disabled, once as rendered.

Scripts disabled
As rendered

0% of pixels differ — they are identical. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
