AI Usage

I would like to acknowledge the use of AI tools in the development of this project. I have NOT VIBECODED the whole project. I have used it for code generation, debugging, and optimization. The entire project is NOT AI-generated, but rather used as a tool in the development process. I am committed to transparency about the use of AI in this project and will continue to provide updates on its role as the project evolves. I use it as a tool to assist in the development process, but the final decisions and implementations are made by me, the developer.
