What to fix first
This element makes the page jump as it loads
header.site-header
p75 CLS is 0.20 on the 29 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 205 ms over 22 page views, mostly on /articles/42/. 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 1.48 s, INP 152 ms, CLS 0.04: that's Google's "good" for each. Watch "Biggest changes" for regressions.
Vitals →
Based on 274 page views. Findings need at least 5 measured page views each, so more show up as traffic grows (try the 30d range).

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.
| LCP | Page views | Clicks per view | Engaged time | Avg scroll |

| Good | 249 | 1.70 | 34.9 s | 59% |
| Needs improvement | 17 | 0.82 | 20.6 s | 67% |
