  # Exceptions are handled depending on request format:
  # * HTML is handled by PublicExceptions, resulting in display of
  #   'public/<status-code>.html' template.
  # * TURBO_STREAM is handled by method specified below, which writes flash
  #   message and forces redirect to referer - to display flash and make page
  #   content consistent with database (which may or may not have been
  #   modified before exception).
  #   This requires referer to be available in TURBO_STREAM format. Otherwise
  #   Turbo will reload 2nd time with HTML format and flashes will be lost.
