def self.call(config)
  # dry-validation/schema does not support "Dynamic Keys" yet: https://github.com/dry-rb/dry-schema/issues/37
  # But :selectors contains mostly "dynamic" keys, as the user defines them to extract article attributes.
  # --> Validate the dynamic keys manually.
  # To be able to specify a `rule`, nest the config under NESTING_KEY and mark that as `required`.
