Returns immediately with a run ID. Poll with GET /workspaces/{workspace_id}/workflows/{workflow_id}/runs/{run_id} for results. Creative Units are not checked here: an underfunded workspace is still accepted and the run then reports FAILURE with error_code BlueprintInsufficientBalanceError. Use the estimate endpoint’s has_sufficient_creative_units to check before submitting.
