I'm continuing development on my Phaser 3 sidescroller game "Vision Quest" and need help refining my LevelTemplate.js file to implement the dialogue and character interaction system based on the game's narrative design.

The dialogue system should follow this flow:

1. Player walks from left to right until hitting a "trigger" zone (collision detection)
2. When triggered, the Shaman character fades in at a predefined position
3. A dialogue box appears with text from my dialogue definition document
4. Player responds via keyboard (Enter to continue or typing responses)
5. Shaman gives a unique response based on player input (will connect to Claude API later)
6. Shaman fades out and player continues to next scene

I've already implemented:

• Complete game structure with 10 scenes
• Character movement and wolf companion
• Scene transitions
• Title screen with menu

Here are the key files from my project that will help you understand the structure:

1. The LevelTemplate.js file that needs refinement
2. GameScene.js which my level scenes extend
3. The dialogue definition document with all conversational content
4. Any entity classes you might need to reference

Please help me enhance the LevelTemplate.js file to include:

1. Trigger zone implementation for dialogue activation
