Big monospace KPI figure with an uppercase label — the IMPADY report's ROI / NPV / payback language as a tile. Lay several in a row for an impact strip.

```jsx
<StatBlock value="189 %" label="ROI" accent />
<StatBlock value="€ 1.686k" label="Net present value" caption="Diskontierte Mehrwerte minus Investments." />
<StatBlock value="6.2 mo" label="Payback" trend="+38 %" />
```

`size` sm/md/lg, `align` left/center, `accent` for orange figure, `onDark` on navy.
