It just depends on what the stack needs to do. In this case, since only 
the mainstack uses a closestack handler, and the mainstack is open at 
card 1 all the time, putting closestack into the card script is fine. 
The handler will always be called. If your mainstack needed to see a 
closestack handler from any card, then it would have to go into the 
stack script (alternately, if all cards shared a background group, it 
could go there.)

If you want the mainstack and all substacks to get the closestack 
handler, put it into the mainstack's stack script.

If you want only some stacks to get a closestack handler, or if your 
mainstack may close from a card other than card 1, put the handler into 
the stack script and do a test inside the handler to see if the right 
stack is frontmost before acting on it.
