/* ══════════════════════════════════════════════════════════════════════════
   investigation_case.css — Investigation Case component (architecture
   refactor: Workflow vs. Investigation separation).

   Reuses global primitives (.qms-section-card, .qms-stats-grid, .qms-table,
   .qms-panel-item, .form-grid, .btn-primary/.btn-secondary, .badge) already
   loaded by qms.css / style.css — this file only adds the Investigation
   Case's own sub-tab strip, visually distinct from the outer deviation
   tabs (.qms-tabs) so Workflow vs. Investigation read as different concepts
   (redesign spec Part 10).
