Site just looks wrong - what have(n't) I done?

at a guess 9/10 sites (you only have to look at any of the showcase sites) you can directly access the stylesheet if you know the relevant path

Using includes/templates/classic/css/stylesheet.css and going through the sites in the Zen Cart Showcase, I was able to read each and every one of the CSS files directly within Firefox on the first page there, with the exception of one that came up with a phishing error
