System monitor
A live operations dashboard — per-core gauges, a streaming history chart, and a live process table sorted by CPU — the kind of thing you’d normally reach for htop or a Grafana panel to build.
In Fleury it’s one widget tree: the same Gauge, Sparkline, LineChart, and DataTable you’d use anywhere, composed with Row/Column and updated on a ticker. No canvas math, no manual redraw bookkeeping — call setState, and the framework repaints only the cells that changed, so the graphs stream smoothly.
Try it: the process table has focus — ↑/↓ move the row selection while the charts stream.
