Story block variation 3

Used in series siderail. Implementation the c-story-block--stacked modifier (no columns at any viewport.) We document these here in the off-chance that the flatblock content is wiped-out. The contents of the block might get out of sync, but the layout classes should remain similar to what's documented here.
