Appearance and themes
The Appearance control in the top bar has two independent axes: a theme family and a mode. Every product exposes both, in the same place.
A theme family is the product’s visual identity — its palette, type and shape. Which families a deployment offers is decided centrally; the standard set is:
| Family | Character |
|---|---|
| Sovereign | The dark-first signature theme. |
| Civic | Neutral, for public administration. |
| Kubernaut | The platform-engineering theme (VNCiac). |
| B-safe | A neutral, green-led theme. |
Mode is System, Light or Dark. System follows your operating system. The two axes combine: any family renders in either mode, and it is the same design throughout, so these instructions match your screen whichever you choose.
How your choice is remembered
