Zones and ownership - who can act in a zone

Module Design
1

Can you create a zone where only a specific player, side, color, can interact with pieces, cards ?

Do I need to use the restrict trait with expressions to test the player playerside against the zone name (or the go I also use for highlighters?)

Thanks all.

Zones don’t have that capability as such, but your proposed solution of using the Restrict trait should work fine.
