## 🧠 Visual Suggestions (for future design)

If you want to create your own SVG for the badge, here's a suggested label:

* **Left:** `License`
* **Right:** `ACUL (Nexus Foundation)`

You can use [Shields.io](https://shields.io/) with a custom label:

```
https://img.shields.io/badge/License-ACUL%20(Nexus%20Foundation)-blue
```

## 📂 Recommended Placement

* In your `.npk.yaml` or `fragment.npk.yaml` file under `license:`
* As a badge in the `README.md` or `docs/index.md`
* Embedded in `nip verify` output for commercial audits

Let me know if you want a branded SVG or PNG with Nexus colors and symbol.
