Based on all my previous selections for characters, world, and visual style, please create a comprehensive and exhaustive master prompt that I can use for all future comic panel generation. The master prompt should:

1. Include detailed descriptions of each character with their roles and visual features
2. Define the world settings and visual metaphors
3. Specify the chosen art style, colour approach, and text treatment
4. Include any special instructions for maintaining consistency
5. Be structured in a way that I can easily modify for different comic panels while maintaining the core elements

Format this as a complete prompt template with clearly labeled sections that I can copy and use directly with AI image generation tools.
