nav.toc > a.toc-link
p75 INP is 204 ms over 6 page views, mostly on /articles/16/. Most of the time goes on running the event handler.

This element makes the page jump as it loads
#onetrust-banner-sdk
p75 CLS is 0.13 on the 3 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.

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.
