Two hotspot badges share an `id`; the later one is skipped.

## What to do

Give every badge in one [`session.overlays.hotspots.set(badges)`](../api/Overlays.hotspots.set.md) call its own `id`; the later badge with a repeated id was skipped.

```ts
session.overlays.hotspots.set(points.map((p, i) => ({ id: `spot-${i}`, at: p.at, label: p.label })));
```

## Where the declaration names it

- [`HotspotBadge.id`](../api/HotspotBadge.id.md): A repeated id records 'hotspot-id-taken'.
- [`Overlays.hotspots.set`](../api/Overlays.hotspots.set.md): Errors: throws HoloInputError on invalid badges; a repeated `id` records 'hotspot-id-taken'.

The set is open: handle a code you don't know (`'other'`).
