One-line: pointer-anchored actions on a canvas item, a file row, a calendar slot. Always mirror the same actions somewhere discoverable.

```jsx
<ContextMenu items={[{label:"Rename",icon:<PencilIcon />},{separator:true},{label:"Delete",variant:"destructive"}]}>
  <div className="o-card" style={{padding:24}}>Right-click me</div>
</ContextMenu>
```
