header.site-header
p75 CLS is 0.12 on the 9 page views where it shifted, mostly on /articles/8/.

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 | 25 | 1.80 | 47.2 s | 59% |
| Needs improvement | 1 | 1.00 | 6.8 s | 37% |
