Use n8n credentials.\n- Avoid exposing employee PII in logs.\n- Sanitize free text before sending emails.\n\nSuccess criteria:\n- Employee matched correctly.\n- Approval branch triggers when manager exists.\n- Clear emails generated (sanitized) for manager and Procurement.\n- Notifications sent and final pages rendered without errors.\n"
