To give you an idea of what I'm thinking of, I've looked into https://github.com/dennybritz/neal-react (unfortunately the hosted demo appears to no longer be up.) I'm sure this will bring out the "JavaScript shouldn't be abused like this!" haters, and I'm not the biggest React fan, but I like that I can position a few high-level components without having to think "I need 2 divs, one that's a panel, one that's X width and another 12-X, etc." Granted, I've never built anything with this React library and don't even know if it looks good, but it's closest to what I want in a page design system. Just give me a few high-level blocks that are responsive and look good, and I'll go from there.
