{# 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. CPU, memory
   and load within the host's own normal for the hour read healthy (#5742),
   with what is usual on hover. Reachability
   and uptime belong to the Monitors widget, so they aren't repeated here. #}
