+== Architecture
+
+=== Overview
+
+This repository follows a modular, maintainable architecture designed
+for clarity, scalability, and long-term sustainability.
+
+=== Directory Structure

+
+=== 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
