## Ejemplo

```tsx
import { FnNumberInput } from '@fn_library'

<FnNumberInput
  label="Precio"
  value={price}
  onChange={setPrice}
  min={0}
  max={10000}
  step={0.01}
  prefix="$"
  description="Precio unitario en USD"
/>
```

## Notas

Wrapper sobre Mantine `NumberInput`. Soporta prefix/suffix para decorar el valor visualmente. Los controles de incremento/decremento respetan min/max/step.
