# Lux Lab interface

The Lux Lab interface divides the app into regions for project files, code editing, agent chat, panel output, and instance status.

## Interface regions

When you open a project, the Lux Lab interface is composed of the following primary regions:

```
┌─────────────────────────────────────────────────────────────┐
│  Workspace tabs              Run  |  Preview  |  Deploy      │  ← Top Bar
├────┬──────────────┬──────────────────────────┬──────────────┤
│    │              │                          │              │
│ A  │   Project    │      Code Editor         │  Agent Chat  │
│ c  │   Explorer   │  (tabs + breadcrumb)     │    Panel     │
│ t  │              │                          │              │
