The stack is in the path of the cards, so often handlers can be written 
either place.

You can put common handlers shared by all cards (and all controls on 
cards) in the stack script.

Usually card specific handlers are put in the card script.

Card messages are sent to the card.  System stack messages are often 
sent to the first card.  Often they are handled in a card script to 
avoid message path problems if the stack is in the message path for 
other objects.

The startup handler has to be in the card script or the stack script, I 
forgot which.
