Biggest movers

Sites whose performance score moved more than this group's normal run-to-run noise. Everything else is jitter and is deliberately hidden.

Leaderboard

Ranked by the circles first — the four Lighthouse categories and axe: all green beats any row carrying an amber, and an amber beats a red, whatever the points say. Core Web Vitals is left out of that, being unknown for most sites here. Rows level on colour are then ranked by the sum of all four Lighthouse categories, then fewest failing Core Web Vitals from real users, then fewest axe violations, then Speed Index per KB — so a fast heavy site outranks a fast empty one.
