## Overview

MealMate is a Django/MySQL food-rescue marketplace. Users and businesses enter through Django routes and account views; users discover and reserve available food, while businesses manage posts and reservations. The product also documents rescue handoffs, demand forecasting, impact and reliability reporting, food interests, notifications, and reservation extensions. The model layer represents the application’s persisted records. Several feature implementations were not excerpted, so their documented presence is shown without guessing unverified internal call paths.

Main entry points: [`accounts/urls.py`](https://github.com/nayem-r/mealmate/blob/main/accounts/urls.py) (Django routes), [`accounts/models.py`](https://github.com/nayem-r/mealmate/blob/main/accounts/models.py) (Marketplace records), [`accounts/rescue_views.py`](https://github.com/nayem-r/mealmate/blob/main/accounts/rescue_views.py) (Rescue matching), [`accounts/impact_service.py`](https://github.com/nayem-r/mealmate/blob/main/accounts/impact_service.py) (Impact reporting)
