Another solution that comes to mind is to have a system where nodes of the similar node groups (let’s say cards in this case) that allows only one of these elements to be selected/hovered etc (either via some sort of event bus or singleton).
Also I’ve stumbled across another post which covers similar issues.
Seems like there’s really no easy way out…
EDIT: found a youtube video covering this exact topic and it talks about different implementations of this and their pros and cons
