// WorkflowNode is a THIN WRAPPER over the shared FlowNodeCard: the card frame,
// handles and icon slot are FlowNodeCard's job (covered by its own spec), so
// these tests cover what the WRAPPER owns — the node-type meta lookup
// (icon / ioType / label), the per-type body, the test-result badge, the
// hover-delete and the hover-`+` step picker.
//
// FlowNodeCard is stubbed (it renders the slots inline and records the props it
// receives); the REAL useWorkflowCanvas singleton is used so the wrapper's
// effects are asserted on actual `workflowObj` state.
