# Nebula Desktop UI

React UI for Nebula Desktop shell chrome. It does not host application or game windows. Those render as Wayland / XWayland surfaces. The native host in `shells/desktop/native` will load this UI in WebKitGTK.

## Surfaces

The same codebase can render each Wayland layer on its own:

| URL | Renders |
|-----|---------|
| `/?surface=preview` (default) | Combined browser mockup |
| `/?surface=desktop` | Background layer only |
| `/?surface=topbar` | Top bar only |
| `/?surface=launcher` | Launcher only |

The native host chooses the origin. Surface selection is a relative query parameter, not a hardcoded port.

## Develop

Oxlint is the linter for this project.
