**Stat** — a dashboard KPI. Value is set in tabular mono so columns of numbers align. Use for channel counts, active streams, uptime.

```jsx
<Stat label="Active streams" value="7" icon={<Ico n="Radio"/>} delta="+2" deltaTone="up" />
<Stat label="Channels" value="128" />
<Stat label="Uptime" value="14d 06h" />
```

Props: `label`, `value`, `unit`, `delta`, `deltaTone` (up·down·neutral), `icon`.
