Edit: Sorry for flippancy. I sense the challenge of the over-complete demo. Eventually, the design requires interfacing with developers who are then skewered for not getting it done as fast as the drag and drop mock-up.
It's probably not horribly worse than taking on an HTML5 template from your favorite template garden along with a laundry list of breaking customizations... I find it pretty quick to take the static images and build out without the baggage of more opinionated style work already "complete"
