module ErrorMessagesHelper

  # Renders a record's validation errors.
  #
  # This replaces the helper of the same name from the dynamic_form gem, which
  # is unmaintained and cannot be installed on Ruby 3.4. The markup matches what
  # that gem produced, minus the heading and description which the
  # errorExplanation styles have always hidden, and matches the structure
  # ajax.coffee builds when it renders errors from a remote form.
