Migrations 037 (workflow tables + 3 seed definitions) + 038 (output_types.workflow_definition_id). WorkflowDefinition/Run/NodeResult SQLAlchemy models in domains/rendering/models.py. workflow_builder.py: dispatch_workflow() with Celery Canvas for still/turntable/multi_angle. workflow_router.py: CRUD endpoints at /api/workflows (admin/PM guards). dispatch_service.py: dispatch_render_with_workflow() prefers workflow path when OutputType.workflow_definition_id is set, falls back to legacy dispatch otherwise. main.py: registers workflows_router. models/__init__.py: re-exports WorkflowDefinition, WorkflowRun, WorkflowNodeResult.
