Okay, so after some searching around, it appears to just use the standard promotional content as set by the mobile main page editor (see here). However, since only admins can see what is set for this, I cannot confirm that this is indeed how the Star Wars wiki has done it. All I can say is that this is what gets used for the wikis I admin.
