## Overview

CERARIA is a premium-tile e-commerce application. The visible customer workflow is product discovery: a visitor requests filtered product listings or a product by ID, and the server queries PostgreSQL and returns product data. Administrators authenticate and use the admin interface to manage products, catalogues, gallery images, and site content; the server persists records and handles uploaded media. The README is empty, and the tree does not expose storefront source, so customer-side wiring and checkout behavior cannot be established from the available evidence.

Main entry points: [`server.js`](https://github.com/sreeharicnair143/ceraria-private-limited/blob/main/server.js) (HTTP API), [`public/admin_script_4.js`](https://github.com/sreeharicnair143/ceraria-private-limited/blob/main/public/admin_script_4.js) (Admin interface)
