## Overview

Puddle is a Django marketplace for browsing and searching unsold listings, creating and managing item listings, and contacting sellers through item-specific direct messages. A user request enters through the URL configuration and is dispatched to views; those views validate forms and read or update marketplace and account data before rendering templates or redirecting. The graph includes the documented profile and admin capabilities. Source was sampled for models, forms, views, settings, and routes; unsampled template behavior is represented only as rendered output.

Main entry points: [`core/views.py`](https://github.com/callmekriztal/marketplace/blob/main/core/views.py) (Request views), [`marketplace/urls.py`](https://github.com/callmekriztal/marketplace/blob/main/marketplace/urls.py) (URL routing), [`core/models.py`](https://github.com/callmekriztal/marketplace/blob/main/core/models.py) (Marketplace models), [`core/admin.py`](https://github.com/callmekriztal/marketplace/blob/main/core/admin.py) (Admin site)
