This may not be an ideal solution, but the immediate thing that comes to mind is to pushEvent from client → server when the viewport causes a pagination size change. That would involve a small amount of JS but not much. The server could then take that into account for its pagination (possibly re-rendering the items because small → large would need more data).
I’ve never had to deal with this, so curious if anyone has creative ideas here. I initially thought of creative CSS to limit the size of the items, but that would mess up pagination since the server needs to know that 6 are being displayed so it can show items 7-12 after 1-6.
