{# alerts/_rule_fields.html — the resource and metric pickers for one source;
   the rule form includes it and swaps it in again when the source changes.
   For a source whose resources are hosts, the rule can instead cover every
   host, or every host in an inventory group (#5464): Steward then keeps one
   rule per host under it. What a rule covers is fixed once it exists. #}
