{# Spec 155 - unused destination table section, rendered on the
   opportunity detail page when the anchor's opportunity_type is
   "unused_destination_table". Separate from the Materialization
   section because the question it answers is different: "should
   this table exist at all?" rather than "how should it be
   persisted?".

   Inputs from the route:
     ``unused_candidates`` - list of evidence_snapshot dicts (one
        per orphan opportunity on this affected_table); each carries
        the standard reasoning block + caveats shape.

   Renders nothing when the list is empty, so the partial can be
   included unconditionally from detail.html. #}
