## Overview

This repository contains several FastAPI examples; the substantial product represented by the central source index is the Carpet Store backend. Its main workflow serves shop and carpet browsing, creates orders from active inventory, then supports checkout and payment-status updates. Staff, authentication, user management, and image uploads are distinct capabilities. The graph preserves these areas and core infrastructure; several service-to-router and database connections are not visible in the excerpts, so they are omitted rather than inferred.
