{# hosts/overview_widget.html — the dashboard Hosts widget (#5251): a verdict,
   then one row per host, worst first, with its resources under one header.
   Load is shown against the host's cores and graded per core. Reachability
   and uptime belong to the Monitors widget, so they aren't repeated here. #}
