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.
| Metric | Lab Simulated | ||
|---|---|---|---|
| Value | Change / range | Trend | |
| LCP CWV (estimate) Largest Contentful Paint | 1.25 s good | ↑ +25 ms (+2%) 1.19 s – 1.26 s | |
| INP CWV Interaction to Next Paint — field only, no lab run can measure it | n/a | — | |
| CLS CWV (estimate) Cumulative Layout Shift | 0 good | → no change 0 – 0 | |
| TBT Total Blocking Time | 0 ms good | → no change 0 ms – 27 ms | |
| FCP First Contentful Paint | 1.13 s good | ↑ +26 ms (+2.3%) 1.11 s – 1.19 s | |
| Speed Index | 2.68 s good | ↑ +129 ms (+5.1%) 1.64 s – 2.69 s | |
| TTFB Time to First Byte | 801 ms needs work | ↑ +25 ms (+3.2%) 776 ms – 863 ms | |
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.
Page weight
| Metric | Value | Change / range | Trend |
|---|---|---|---|

| Third-party CPU | 0 ms | → no change 0 ms – 0 ms | |
| Unused JS | 0 B | → no change 0 B – 0 B | |
| Unused CSS | 0 B | → no change 0 B – 0 B |

Without JavaScript
The same load, photographed twice at 412×823: once with scripts disabled, once as rendered.
0.2% of pixels differ — they are nearly identical. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
Page health
| Metric | Value | Change / range | Trend |
|---|---|---|---|
