## Overview
Shivam is a CodeIgniter-based e-commerce website. The principal request path is a shopper reaching a routed page or storefront controller and receiving a rendered view; the tree also shows account, cart, order, product, and administrative areas. The graph includes the framework’s bootstrap, routing, loading, and session layers. Source excerpts are limited, so many application-to-model and model-to-view relationships are shown as unverified rather than asserted.
Main entry points: [`system/core/CodeIgniter.php`](https://github.com/shivam123-vb/shivam/blob/main/system/core/CodeIgniter.php) (Runtime Bootstrap), [`application/views/admin`](https://github.com/shivam123-vb/shivam/tree/main/application/views/admin) (Admin Views), [`system/database/DB_query_builder.php`](https://github.com/shivam123-vb/shivam/blob/main/system/database/DB_query_builder.php) (Database Layer), [`application/views/product_list.php`](https://github.com/shivam123-vb/shivam/blob/main/application/views/product_list.php) (Storefront Views)
