Mobile visitors get a much slower INP
p75 INP is 314 ms on mobile against 145 ms on desktop. Mobile is 49% of your page views.
Try: Test on a real mid-range phone or with CPU throttling: big images, heavy JavaScript and third-party scripts cost far more there.

This element makes the page jump as it loads
header.site-header
p75 CLS is 0.12 on the 7 page views where it shifted, mostly on /articles/16/.
Try: Reserve its space before it arrives: width and height (or aspect-ratio) on images and embeds, a min-height for content inserted later, and font-display with matched fallback metrics for web fonts.

Taps and clicks on this element respond slowly
button.add-to-cart
p75 INP is 282 ms over 6 page views, mostly on /articles/16/. Most of the time goes on running the event handler.
Try: The event handler itself is slow: do less work in it, or yield (scheduler.yield / setTimeout) before the heavy part.

All three Core Web Vitals pass
p75 LCP 1.63 s, INP 175 ms, CLS 0.03: that's Google's "good" for each. Watch "Biggest changes" for regressions.

Does speed cost engagement?
Page views grouped by their own LCP. If slower pages get fewer clicks and less reading, that's the cost of slowness.
