Architecture

This core package provides the "cookbook and pantry" for AndyChat implementations:

• API Logic: All backend communication
• Design Tokens: Consistent styling system
• Utilities: Common functions for parsing, validation, etc.
• Configuration: Centralized settings management

Both @andesphereai/vanilla and @andesphereai/react use this core package for all business logic while implementing their own UI layers.
