Hello,

I think I see the point, and I would say that you still need some kind of link between your App and your Lib. If no extra action is needed on the mapbox css, I would simply compile it when the Lib compiles, this will produce the myLib.css file and you will simply have to reference it in your myApp.scss file (providing there is no extra asset to expose). I think it's a nice use case, I will look into it anyway.
