{# plugins/prometheus/templates/prometheus/template.html — one widget
   template (#5692): its YAML beside a live preview over a chosen target,
   drawn as the dashboard widget draws it. An admin edits their own here,
   or starts one by pasting or uploading; a built-in one is read-only and
   can be duplicated. The preview saves nothing. #}
