How sanjay-05/book_management_system works

This is a Gin-based Book Store API. Its principal workflow is an HTTP request routed through public or role-protected routes to a handler, then through business services to repository operations backed by PostgreSQL; handlers return API responses. The domain spans identity and password recovery, catalog and contact administration, user profiles, carts, and order checkout/status. The source excerpts show representative calls across these layers, but not every route or subsystem implementation; README-documented capabilities are retained without inventing their internal wiring.
