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.

| LCP CWV (estimate) Largest Contentful Paint | 1.35 s good | ↑ +194 ms (+16.7%) 1.16 s – 1.38 s | |
| INP CWV Interaction to Next Paint — field only, no lab run can measure it | n/a | — | |
| CLS CWV (estimate) Cumulative Layout Shift | 0.004 good | → no change 0 – 0.004 | |

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.

Without JavaScript
The same load, photographed twice at 412×823: once with scripts disabled, once 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.
