Added a custom greetings popup to give Cosmic Lens a warm, personal touch! Fixed a CSS bug where the popup styling was trapped inside a mobile media query. I also resolved a JavaScript selector typo and removed it from JavaScript so the popup only depended on index.HTML so the close button works smoothly. Also cleaned up robotic AI comments and removed divider lines from the code. Finally ready to reship with a personalized README and an authentic codebase!
