/******************************************************************************

PBS KIDS JS Namespace.

This namespacing arrangement is designed to guard against PBS KIDS JS
accidentally clobbering producer, station or 3rd party JS that pre-exists a
deployment.

It's also designed not to clobber a pre-existing top-level PBS node. If such
a node exists, we simply add our KIDS node to it.
