How external request share shapes main-thread contention and INP

Third-party request share measures the fraction of page requests served from external origins. Across 32,405 sites (51.2%) keeping third-party traffic under 10% and 21,262 sites (33.6%) between 10% and 25%, good INP reaches 100% and 100% (46ms and 49ms median). When third parties account for 25% to 50% of requests (12.1%), good INP drops to 99% (52ms median), while the 3.1% over 50% sit at 99% good INP (50ms median).
