## Scene Graph

### `main_menu.tscn` — entry point
```
MainMenu (Control)   ← main_menu.gd builds all UI in _ready()
```

### `world.tscn` — game world
```
World (Node2D)
├── TextureRect              ← static space background (skybox/1.png)
├── Player                   ← instance of node_2d.tscn
├── HUD (CanvasLayer)
│   └── HealthLabel
├── PauseMenu (CanvasLayer, layer=10)   ← pause_menu.tscn
└── TeamSelect (CanvasLayer, layer=20)  ← team_select.tscn; queue_free()s after selection
```

### `node_2d.tscn` — player ship
```
Player (CharacterBody2D)   ← ship_movement.gd
├── CollisionShape2D        ← CircleShape2D
├── Sprite2D                ← texture set at runtime from GameConfig.player_ship_path
└── VisibleOnScreenNotifier2D
```

## Input Map

| Action | Key | Controller |
|--------|-----|------------|
| `move_up` | W | — |
| `move_left` | A | — |
| `move_right` | D | — |
| `move_down` | S | — |
| `shoot` | Space | — |
| `toggle_pause` | Esc | Start / Options button (JoyButton 6) |

## Game Flow

```
main_menu.tscn
  ├── CASUAL → world.tscn
  │     ├── TeamSelect overlay: pick race (2 random of 3 offered)
  │     ├── TeamSelect overlay: pick ship
  │     └── Player spawns → game live
  └── RANKED → disabled (coming soon)
```

> **Note:** `server_browser.tscn` was built (Task 1) and is functional, but the current flow bypasses it — CASUAL goes directly to the world and TeamSelect handles name/race/ship. The server browser will be re-integrated when real multiplayer server listing is built.
