- Removed unused showcase toggle functionality from ModelCard and ModelModal. - Simplified metadata panel handling in MediaUtils and MetadataPanel, transitioning to button-based visibility instead of hover. - Enhanced showcase rendering logic in ShowcaseView to support new layout and navigation features. - Updated event handling for media controls and thumbnail navigation to streamline user interactions. - Improved example image import functionality and error handling. - Cleaned up redundant code and comments across various components for better readability and maintainability.
