world's most petty problem (Dreamwidth layouts edition)

So! Josh told me recently that there were DW layouts without sidebars, and I have managed to find one, and I fiddled with all the colors until I came up with something that seemed plausible. But! There is one tiny problem remaining: it's drawing little pink borders a few px out from everyone's icon, such that you notice pink and not whatever color people have chosen for the border of their icon (or messing up the borderlessness). Does anyone have any idea where this feature is in the customization, so I can turn it off? I can't find it. (Pink was one of the original colors of the theme, but I de-pinked it because bleah.)

ETA: fixed! Apparently this is something that changes from, uh, theme to theme within the same, uh, archtheme?
