Backend: GET /api/v1/system/performance endpoint using psutil (CPU/RAM) and nvidia-ml-py (GPU utilization, memory, temperature) with graceful fallback. Frontend: Chart.js line charts with rolling 60-sample history persisted to sessionStorage, flicker-free updates via persistent DOM and diff-based dynamic section refresh.
