History from the previous URL is included below, with the move on Sep 5, 2026. A step-change around that point is likely the change of address rather than a regression.
Lighthouse benchmark index was 3,946, 59% faster than this project's median of 2,487. CPU-bound metrics — TBT, TTI, main thread work — are affected by this and may have moved without the site changing at all.
Lab data is measured using Lighthouse, Mobile mode unless otherwise specified. Field data is reported from Chrome UX Report (using p75 measurements).

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

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.
0.8% of pixels differ — they are nearly identical. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
