  Provides HTML error pages.

  If you want to customize the error pages for particular status codes, add
  pages to the `error_html/` directory, such as:

    * lib/admin_web/controllers/error_html/404.html.heex
    * lib/admin_web/controllers/error_html/500.html.heex

  Or, add `render/2` functions, such as:

      def render("404.html", assigns) do
        # ...
      end

      def render("500.html", assigns) do
        # ...
