Hi Jeff,

I would recommend rather duplicating the template perhaps and adding it in theme.php. The reason being, if I add a custom.css it will override your work on every update. If I dont add a custom.css file but I add custom.css in the theme.php file to include by default it will give an error if it can't find it.

Creating your own customized theme will probably be the safest route.
