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.
Lab data is measured using Lighthouse, Mobile mode unless otherwise specified. Field data is reported from Chrome UX Report (using p75 measurements).
