- Add enhanced hover/focus states with accent colors and border transitions
- Implement tabbed interface for priority tags with LoRA, checkpoint, and embedding sections
- Improve input styling with consistent error states and example code formatting
- Remove deprecated grid layout in favor of tab-based organization
- Add responsive tab navigation with proper focus management and visual feedback
