OK I see what you are saying here.  Well one thing that you could do is have a
random-access stylesheet (like a DOM representation) and simply make the
necessary changes dynamically for each stylesheet.  You would still have three
separate stylesheets in a sense, but you would not have the overhead of totally
rebuilding the stylesheet tree if one trivial styling change needed to be made
for multiple stylesheets that does not involve messing around with the source
tree (like background color for example).  This would be the cleanest way of
doing things other than just having separate stylesheets altogether.
