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 | 967 ms good | ↑ +1 ms (+0.1%) 938 ms – 971 ms | |
| 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 – 0 ms | |
| FCP First Contentful Paint | 967 ms good | ↑ +1 ms (+0.1%) 938 ms – 971 ms | |
| Speed Index | 967 ms good | ↓ -129 ms (-11.8%) 954 ms – 1.25 s | |
| TTFB Time to First Byte | 604 ms good | ↓ -1 ms (-0.2%) 604 ms – 609 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 |
|---|---|---|---|
| Page Weight | 55.3 kB | ↓ -55 B (-0.1%) 55.3 kB – 55.4 kB | |

| 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.
0.1% 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 |
|---|---|---|---|
| Main Thread Work | 208 ms | ↑ +3 ms (+1.4%) 160 ms – 224 ms | |
| Long Tasks | 0 | → no change 0 – 0 | |
| DOM Elements | 739 | → no change 739 – 741 | |
| Axe Violations Violating nodes from a full Axe CLI run (more than Lighthouse reports) | 0 | → no change 0 – 0 | |
| A11y Failures | 0 | → no change 0 – 0 | |
| A11y Failing Nodes | 0 | → no change 0 – 0 |
