{# /opportunities filter controls.

   Layout: a CSS grid that wraps onto two rows on desktop
   (Search | Issue | Workload | Suggestions on row 1;
   Dataset | Author on row 2). Each control is one line via the
   filter components.

   The Partition / Cluster filter was removed in spec 154 v2 along
   with its table column - partition + cluster recommendations are a
   data-lineage-level signal and belong on /recommendations/layout,
   not on a per-job listing.

   Collapsed by default; auto-opens when any signal is non-empty.
   See ``components/_filter_form.html`` for the wrapper behaviour. #}
