Happy page views

13% of these page views were in-app (soft) navigations. Those report INP and CLS, but browsers only measure LCP, FCP and TTFB on full page loads, so those three cover fewer page views.
What to fix first
Taps and clicks on this element respond slowly
nav.toc > a.toc-link
p75 INP is 237 ms over 3 page views, mostly on /articles/8/. 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.
INP by element →
Based on 8 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 | 7 | 1.29 | 20.7 s | 40% |
| Poor | 1 | 1.00 | 11.0 s | 64% |
