# Overview

The `display` module is the Core GUI surface. It coordinates windows, menus, trays, dialogs, notifications, and WebSocket events through **Wails v3** on the Go side and **Angular** in `ui/` on the frontend side.

## Architecture

The project consists of two main parts:

1.  **Backend (Go):** Handles window management, tray/menu setup, dialogs, notifications, layout persistence, and IPC dispatch.
2.  **Frontend (Angular):** Provides the user interface. It lives in `ui/` and is built as a custom element that talks to the backend through the Wails runtime.

## Key Components

### Display Service (`display`)
The core service manages the application lifecycle and exposes declarative operations such as:
- `OpenWindow(window.Window{})`
- `CreateWindow(window.Window{Name: "editor", URL: "/#/editor"})`
- `SetWindowBounds("editor", 100, 200, 1280, 720)`
- `SaveLayout("coding")`
- `TileWindows(window.TileModeLeftRight, []string{"editor", "terminal"})`
- `ApplyWorkflowLayout(window.WorkflowCoding)`

### System Integration
- **Menu:** The application menu is constructed in `buildMenu()` and dispatched through IPC.
- **System Tray:** The tray menu is configured in `setupTray()` and keeps the desktop surface in sync with the runtime.
- **Events:** Window, theme, screen, lifecycle, and tray actions are broadcast as WebSocket events for the frontend.
