Forum post text/font issue - where is this font setting?

I'm working on rebuilding my 3.x skin under vb4, and am slowly making progress. One thing I can't seem to sort is why my modified skin has a different font for the message text than the vb4 default theme.

Here's a post with the default theme. This is the font that I want my skin to have as well:

Here's a post with my theme. I don't know where/what I changed, but the font is definitely different.

Here's a screenshot of the default theme, pasted into mine so that you can see the text difference.



I'm using Firebug, and it looks like this is "blockquote class="postcontent restore". I checked my templates, and this is the same in both of my postbit_legacy templates:

<blockquote class="postcontent restore ">

In my style variable editor, postbit_font is the same for both themes as well:

Font Family: Verdana,Arial,Tahoma,Calibri,Geneva,sans-serif
Units: px
Size 13

It's also not showing as red (edited) in my custom skin. Is this not where you change the font? Where else is the text actually defined?

Any insight would be great - it's been a while since I tried to wrap my head around the "new" (to me anyway) style system and I'm having a heck of a time with it.
