Backend (FastAPI) Documentation
===============================

Welcome to the documentation for the **Backend** of the *AILA Chatbot*!  

This section provides a complete reference to the backend system, which is built with **FastAPI**.  
It explains the architectural design, core functionality, and the public API surface generated from inline docstrings across the backend modules and packages.  

The backend is responsible for:  

- Managing authentication and user sessions  
- Handling real-time WebSocket communication for chat  
- Integrating the Retrieval-Augmented Generation (RAG) pipeline  
- Serving API endpoints to the frontend and external clients
