Dashed, notch-labelled container used in the workflow visuals to show scope — nest it to render AgentOS → Workspace → Projekt.

```jsx
<WorkspaceBox tone="ink" label="AgentOS">
  <WorkspaceBox tone="ink" depth={1} label="Content WS">…</WorkspaceBox>
</WorkspaceBox>
```

Depth 0–2 steps the border colour, radius and label size down; the label knocks out the background, so keep the box on a flat ink or paper floor.
