p75 CLS is now 0.06. The Vitals tab shows when it changed and which pages it changed on.
CLS over time →
This element makes the page jump as it loads
ul.product-grid
p75 CLS is 0.15 on the 3 page views where it shifted, mostly on /articles/37/.
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.
CLS by element →
Taps and clicks on this element respond slowly
nav.toc > a.toc-link
p75 INP is 221 ms over 4 page views, mostly on /articles/37/. 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.

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.
