/**
* Tests that themes do not depend on Stable assets.
*
* These tests exist to facilitate the process of decoupling theme from Stable.
* The decoupling process includes:
* 1. Identifying Stable assets that differ from core ones
* 2. Of those differing assets, identify those that are inherited by
* the themes being tested.
* 3. Determine if a copy of that Stable asset must be added to the theme,
* or if it's acceptable for the theme to inherit the more recent version
* of the asset from core.
* This test will identify these assets and confirm that the theme has properly
* decoupled itself from them by either having a theme-specific copy of the
* asset, or it being determined that it's acceptable for the theme to use
* core's version (in which case it will be skipped by this test).
