Lighthouse Scores LAB Simulated
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 | 2.60 s needs work | ↑ +9 ms (+0.3%) 2.57 s – 3.06 s | |

| CLS CWV (estimate) Cumulative Layout Shift | 0.093 good | → no change 0 – 0.148 | |

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.
87.4% of pixels differ — the page changes substantially. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
