Subject: [PATCH] refactor: Modernize CSS with nested selectors and improved
 styling

Major CSS improvements:
- Refactor to use modern nested selector syntax for better maintainability
- Add comprehensive chat interface styling with animations
- Improve component hover states and interactive feedback
- Add loading indicators and smooth transitions
- Better organization of styles with logical grouping
- Enhanced visual hierarchy and accessibility

This modernizes the frontend styling while maintaining existing
functionality and improving code maintainability.
