Document the possibilities for scenario creation + the game engine features

[Greenheart]

Scenario creation ideas

• Card groups (by looping over specific cards and adding a specific world query looking for a flag set by cards in the previous card group)
• using next to point to a specific card in sequence. Can be used to create linear sections, or a branching narrative (although be careful with them since they add complexity).
• How to add custom icons for your scenario: Embedding the SVG data URL:s for the icons you want. Ideally defined as constants in the icons.ts file.
• How the content utils works: Purpose: Automation of common tasks when creating scenarios. If you create useful helper methods for your scenario, feel free to add them to the shared library if they could be useful for other scenarios too.

Documentation ideas

• Use excalidraw to create nice graphics to explain concepts. Add to the docs folder of the project, and create markdown files that reference the images. Will be easy to view on GitHub, and easy to edit.
• Show common types of scenario situations with graphics
