Tablet visitors get a much slower INP
p75 INP is 300 ms on tablet against 136 ms on desktop. Tablet is 13% 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.

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.
