My apologies, I have made a mistake. It appears that the JS already imports the base CSS. So the above is actually redundant (meaning you can re-delete MediaWiki:ReferencePopups.css and remove the import statement from MediaWiki:Common.css). However, you would still need to restore the customizations you tried to make on MediaWiki:Wikia.css. However, looking at them, I believe the reason you don't see any changes is that the CSS you put there is identical to that in the default CSS.
