Global pages like MediaWiki:Wikia.css affect all pages, so the number of articles a wiki has is not important. The tricky part with cursors is that simply apply it ont he body of the page doesn't change other states of cursors, like hovering above links, etc..

For a situation like this, you would need to use a more advanced CSS code, and also use JavaScript to add/ remove classes for certain events (e.g. dragging objects).
