Subject: [PATCH] Title: Performance optimization and code modernization

Key features implemented:
- Added comprehensive .gitignore file to exclude compiled artifacts, dependencies, logs, editor files, and build directories
- Refactored script.js with performance optimizations including DOM element caching, preloaded audio, and optimized class manipulation
- Implemented event delegation and improved audio handling with error catching and proper pause/resume functionality
- Added global audio player controls and improved click target detection to prevent event bubbling issues

The changes significantly improve performance through DOM caching and optimized event handling while maintaining all existing functionality with better code organization and error handling.
