Can CSS and JS libraries be made available at a CDN?

Yes! The CSS/JS used by your system can be made available via a content delivery network (CDN) using many different options. Since Knapsack enables Engineering teams to use their own Continuous Integration workflows to build all source files, it's simple to deploy them to any CDN you choose as part of that flow. 

If the design system is published as a public NPM package, then the CSS/JS is automatically available on the free CDN via http://unpkg.com.
