Tiny uppercase kicker chip that tags a card, post or section ("INTERVIEW", "NEU", "SYSTEM").

```jsx
<Pill tone="violet">INTERVIEW</Pill>
<Pill tone="neu">NEU</Pill>
<Pill tone="label">label pill</Pill>
```

`section`/`label` are for ink surfaces, `violet`/`quiet` for paper, `neu` (swissAI pink) and `highlight` (atrete lime) are signal chips — one per view.
