Built an e-commerce app (BlueMart) with Flask & PostgreSQL. Roast my UI / feedback welcome!

Hey everyone,
I was tired of doing isolated coding exercises that didn't feel real, so I decided to build a complete full-stack project from scratch to test my skills.
It's an e-commerce web application called BlueMart, built using Python Flask and PostgreSQL.
Key features I've implemented so far:
• User Authentication: Secure signup and login flow.
• Store Management: Dynamic product listings and inventory management.
• Shopping Workflow: Working cart functionality and order processing.
• Admin Dashboard: A centralized place to track metrics and data.
• Database Integration: Relational database architecture using Postgres.
I’m actively trying to level up my full-stack development skills, so I would highly appreciate any constructive criticism you have on the UI, user flow, or performance.

BlueMart is a full-stack e-commerce web application built using Python Flask and PostgreSQL.

This project was built to transition away from isolated coding exercises and master real-world, full-stack application development challenges—such as state management, relational database design, and user authentication.
