+/**
+ * @fileoverview For ContentTask.spawn, this will automatically declare the
+ *               frame script variables in the global scope.
+ *               Note: due to the way ESLint works, it appears it is only
+ *               easy to declare these variables on a file-global scope, rather
+ *               than function global.
