🏗️ Go Project: Three-Layer Architecture (Clean Code Example)

This project demonstrates a Three-Layer Architecture in Golang with unit testing and mock integration, using:

• net/http for handlers
• A custom service layer for business logic
• A store layer for data access
• Fully unit-tested using Go’s testing package and mock functions
