Subject: refactor: LightBox and Shadow classes for clarity and reuse

Added section comments and reorganized methods in both LightBox and Shadow for better readability. Shadow now supports finding existing instances, tracks open state, and separates initialization logic. Improved animation handling and event binding for closing shadows.
