Key Implementation Notes

• Front Controller: public/index.php routes requests using query parameters (e.g., ?target=product&action=index).
• Singleton Pattern – Used for managing a single instance of the PDO connection across the application
• Security: Sensitive files are stored outside /public. Seller-only routes are protected via session-based role checks.
• Responsive Design: The application uses Bootstrap 5 to support both mobile and desktop devices.
