Accessing a Meteor app's CSS programmatically

I was looking for how to access the URL to a Meteor app's CSS files. After not finding anything, I read through some source code and came up with the following snippet:

if (Meteor.isServer) {
  var cssUrl = _.pluck(_.filter(
    WebApp.clientPrograms['web.browser'].manifest, function (i) {
      return i.type === "css";
    }
  ), "url");
}

I needed this when creating some server-rendered spacebars templates. For easy, non-reactive server-side rendering, try David Burles' spacebars-tohtml.
