# This specs the behavior of the Stylesheet and Javascript models where they
# share much the same behavior (this is better than spec-ing the TextAsset model
# since, frankly, we care about the Stylesheet and Javascript models, not their
# parent).
#
# In the future, should unique behaviors appear, they would go at the bottom of
# this spec or in their own specs.
