{# alerts/widget.html — the dashboard Alerts widget (#5510), in the widget
   shape (snippet #5259): a verdict; what is firing or silent, its reading
   now against what the rule fires on, and since when; then what someone has
   acknowledged, by whom and when; a line when alert email is failing or
   retrying; the quiet rules counted. Rows come from alert_svc.active_rows,
   so they read in the Alerts page's order. #}
