A contrast matrix for a phoenix_storybook page story, one tab per theme.

defmodule Storybook.Accessibility.Contrast do
  use PhoenixStorybook.Story, :page

  @css "assets/css/app.css"
  def navigation, do: ExcessibilityStorybook.ContrastPage.navigation(@css)
  def render(assigns), do: ExcessibilityStorybook.ContrastPage.render(assigns, @css)
end

The stylesheet is re-read on every render, so editing a token shows up on reload.
