I am trying to find which file(s) to modify to add a CSS import for a font, as highlighted as possible. This NetSuite document points out that this is possible, and seems trivially easy to do. However, it lacks any reference as to "what" file in what I assume to be the theme's Modules folder I should add my "@import url(..." to?

If someone could highlight where exactly I should be adding this to, or how best to implement it, as well as any further instruction for implementing a custom font, that would be great.
