🚲 Bike Shop Inventory Management (Spring Boot)

This project is a Spring Boot web application that allows users to manage inventory for a bike shop.
It includes functionality for managing in-house parts, outsourced parts, and products, along with custom validation rules and a responsive UI.

⚠️ Note: Database integration is currently in progress. Some features may not work properly until DB implementation is finalized.
