The measuring machine was faster than most in this project.

Lighthouse benchmark index was 4,057, 64% faster than this project's median of 2,480. CPU-bound metrics — TBT, TTI, main thread work — are affected by this and may have moved without the site changing at all.

The same load, photographed twice at 412×823: once with scripts disabled, once as rendered.

Scripts disabled
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.
