Major UI overhaul for TuneRipper: removed sidebar navigation, refactored layout to a centered, single-page experience with a modern hero section and input form for YouTube-to-MP3 conversion. Added new logo and high-res icons (logo.png, icon-192.png, icon-512.png), updated favicon and app icons, and introduced manifest.json for PWA support. Removed Counter, Weather, and NotFound pages; improved global and page-specific CSS for branding and responsiveness.
