Mobile visitors get a much slower INP
p75 INP is 266 ms on mobile against 151 ms on desktop. Mobile is 50% 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
div.ad-slot
p75 CLS is 0.20 on the 87 page views where it shifted, mostly on /.
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
nav.toc > a.toc-link
p75 INP is 273 ms over 58 page views, mostly on /search/. 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.

/search/ pages are slow to show their main content
p75 LCP is 2.58 s over 80 full page loads; 11% took over 4 s. Most of the time goes on waiting for the server.
Try: Most of the time passes before the HTML arrives: cache pages at the edge/CDN or speed up the server.

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.
