feat: implement absolute positioning for slide editor with viewport-aware layout
## Major Improvements: ### Absolute Positioning System - Implemented fixed positioning for slide editor to break out of DOM flow - Editor uses full viewport (top: 80px; left: 0; right: 0; bottom: 0) - Fixed header at top with z-index layering for proper overlap - Background overlay to separate from underlying content ### Viewport-Optimized Layout - True 50/50 split using full available viewport width - Height calculations based on actual viewport (100vh) not container constraints - Responsive top positioning (80px desktop, 60px tablet, 50px mobile) - No scrolling issues - content always fits within viewport boundaries ### Enhanced Live Preview - Applied presentation aspect ratio classes to preview container - Dynamic aspect ratio detection (16:9, 4:3, 16:10) - Viewport-aware sizing with proper aspect ratio preservation - Added aspect ratio indicator in preview meta information ### Improved User Experience - Compact header design with reduced padding and font sizes - Internal scrolling for content fields while keeping actions visible - Better space utilization with reduced margins and gaps - Consistent behavior across all screen sizes and orientations ### Technical Enhancements - Z-index management for proper layering (header: 20, content: 10) - Flexbox structure for optimal space distribution - Overflow handling for different content types - Mobile-responsive design with appropriate scaling 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
