CSP is Responsive Design

This is a great post! Very nicely written and understandable. I really like the way this approach breaks up the work of reacting to, processing, and rendering the results of events into discrete and composable steps. I feel like I'm starting to understand the potential power behind CSP for user interface development.

I do wish that it included a full code listing, though. I'm curious to see how the code looks in its finished state, together with whatever additional helpers need to be defined to accomplish what we see on the page. I'm also interested to know how the protocols the article defines get implemented and used.
