Literally, the first card of *your* main stack.

In your case there is only one card but the method still applies: whenever
you need to initialize stuff, placing the init scripts in the first card of
your main stack limits causes the scripts to run only when the main stack is
opened (preOpenStack, openStack, openCard, etc).  Subsequent opening/closing
of substacks or IDE stacks will not trigger your card scripts because they
are not part of the other stacks' message hierarchy.
