/* Kodza — Alert
   A message that sits in the page: a note (default), --success, --warning or --error.
   Monochrome: the kind is said by the icon's shape, and an error is inverted, ink on ink.
   The icon draws itself when the alert shows up; dismissed, it folds away and what follows
   slides up instead of jumping. An error can unfold its details (a log, a stack trace).
   Remove [hidden] to show one again, it unfolds the same way.
   Everything is tuned with the --kz-alert-* variables. */
