-## Design Principles
-
-- **Separation of Concerns**: Each module has a single responsibility
-- **Testability**: Code is written to be easily testable
-- **Documentation**: All public APIs are documented
-- **Configuration**: Environment-specific settings are externalized
-
-## Dependencies
-
-- External dependencies are minimized and clearly declared
-- Version pinning is used for reproducibility
-
-## Security Considerations
-
-- Sensitive data is never committed to the repository
-- Secrets are managed through environment variables or secure vaults
-- Regular dependency audits are performed
-
-## Maintainability
-
-- Code follows consistent style guidelines
-- Pull requests require review and CI checks
-- Issues and discussions are tracked transparently
