Live view of everything captured by SlackSandbox.Inbox, pushed in real
time over PubSub. Mount it directly in your router:
live "/dev/slack-inbox", SlackSandbox.InboxLiveRenders with plain Tailwind utility classes and no external layout, so it
drops into any Phoenix app without pulling in your app's own layout
module. Pass layout: {MyAppWeb.Layouts, :root} as a route option if you
want your app chrome around it.
