Server Side Render

[cogwizzle]

Server Side Render
As a user I would like the server to render my components and then have them replaced once the page is ready so that I don't have page shift as the content is rendered.

Acceptance Criteria
Given I navigate to the app
When the HTML content is returned
Then the content in the application is already filled out based on the class and is updated once the custom elements are added.

Describe the solution you'd like
I would like to use @skatessr or a solution that renders the UI in a headless browser so that I can handle this use case.

Describe alternatives you've considered
Another solution would be to use Lit element, but since my components are already written with native JavaScript it would be a really hard lift.
