// FB-41 (P0 compliance, composition profile — ADR 013): the "Berater-
// Auslastung (letzte 90 Tage)" section must be hideable via the
// `consultantLoadReport` profile flag. Before this flag existed the section
// always rendered unconditionally, so "hidden when false" below is a
// genuine regression test — against the pre-flag component it fails (the
// heading would be found).
//
// FIXTURE-DATEN-REGEL: all props below are empty collections — this test
// only exercises the flag-gated section, not the data-driven rendering
// paths (those are covered by lib/reporting/__tests__/aggregations.test.ts).
