What to fix first
Taps and clicks on this element respond slowly
button.add-to-cart
p75 INP is 686 ms over 4 page views, mostly on /articles/5/. 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.

Mobile visitors get a much slower INP
p75 INP is 291 ms on mobile against 103 ms on desktop. Mobile is 48% 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
ul.product-grid
p75 CLS is 0.14 on the 9 page views where it shifted, mostly on /articles/5/.
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.

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.
