Implement innovative drag-to-adjust interaction in visual comparison view: Visual feedback: - Cursor changes to grab/grabbing when draggable - Active bar scales up and shows ring focus indicator - Hover overlay displays "Drag to adjust" hint - Smooth transitions when not dragging, instant updates while dragging Drag mechanics: - Mouse drag support for desktop - Touch drag support for mobile devices - Logarithmic scale conversion preserves intuitive feel - Clamped percentage range (3-100%) prevents invalid values - Dragging updates input value and selected unit in real-time Technical implementation: - Added onValueChange callback to VisualComparison component - Reverse logarithmic calculation converts drag position to value - Global event listeners for smooth drag-outside-element tracking - Prevents scrolling during touch drag on mobile - MainConverter integrates drag callback to update state This creates a highly tactile, visual way to adjust conversion values by directly manipulating the bar chart representation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
