P75 is green: LCP 1.58s, INP 176ms, CLS 0.01. P90: LCP 2.68s, INP 352ms, CLS 0.17. 15% of visits get a noticeably worse experience.

Product Performance doesn't end once you pass CrUX: if P75 is good, work on P90.

Congrats on the 48% size cut! Curious—did you switch to CSS variables or purge unused styles for the 42% CSS reduction? Also, what ARIA patterns did you add for the new mobile card UI? #webperf

Has your INP worsened since May? ⚠️

The Facebook Pixel may be to blame. AT PageSpeed.ONE, we’re already seeing its growing click-processing workload hurt responsiveness on several client websites.
