def eager_load!
  # Manually eager load `lib/pageflow` as the least bad option:
  #
  # - Autoload paths are not eager loaded in production.
  #
  # - `lib` cannot be an eager load path since otherwise templates
  #   in `lib/generators` are also executed.
  #
  # - `lib/pageflow` cannot be an eager load path since eager load
  #   paths are automatically used as autoload paths. That way
  #   `lib/pageflow/admin/something.rb` could be autoloaded via
  #   `Admin::Something`.
  #
  # - Using `require` in `lib/pageflow.rb` disables code
  #   reloading.
  #
  # - Using `require_dependency` in `lib/pageflow.rb` does not
  #   activate code reloading either since it requires the
  #   autoload path to be set up correctly, which only happens
  #   during initialization.
