Can’t find a font tag in CSS for Default Template

I’m working with the Default Template and am running into an odd quirk. I want the text of a post or a page to be Verdana, and have reset the H1, H2, and H3 on the style sheet to Verdana.

But, while the post text on a page is now Verdana, the post text on the front page is Georgia! There’s no reference to Georgia or a serif font in the style sheet. The header is Verdana but the text is not.

Has anyone run into this? I’m usually good at this, but I’ve never worked with modifying the default template before.
