Update styling to match new Chrome/devtools flat design.

What would you like to be added:

It would be amazing to have a "Deploy with Heroku" button. Someone please help and build this.

Short-term success is having some additional manual tooling and workflows that adds value to the development process and is not burdensome to contributors.

Long-term success would be to run Sorbet type checking as part of the CI lint process (e.g. there is a clean/gree

Currrently , the CLI outputs "No such file or directory" but should be more verbose and explain which file could not be found.

{
  data: {

    type: 'posts',
    attributes: { ... }
  }
}

We pay attention to the payload and not the URL - instead let's throw an error when there is a mismatch.
