First screen: server-side rendering

happens on first navigation

1. @server: p1 = await App.getInitialProps
   • calls Page.getInitialProps in turn
2. @server: const html = ReactDOM.hydrate(<App { ...p1 }>);
3. @server: res.send(html, p2 = JSON.stringify(p1)
4. @client: parse and show html as usual
5. @client: ReactDOM.render()
