Subject: [PATCH] Update script.js

The improved version of the script enhances readability, maintainability, and efficiency while preserving all functionalities. Clear and well-structured comments have been added to each section to improve understanding, making it easier for developers to navigate and modify the code. Variable names have been refined for better clarity, ensuring they accurately describe their purpose. The code formatting has been standardized with consistent indentation and spacing, making it more visually organized. Additionally, unnecessary variables and redundant operations have been removed to optimize performance. The handleStickyNavigation function has been structured more efficiently to ensure smooth execution, and all initialization functions are logically grouped for better organization. These improvements collectively make the script more professional, maintainable, and scalable while ensuring a seamless user experience.
