🔍 Technical Improvements

Positioning Engine

// New proportional scaling system
const getDisplayPositions = () => {
  return Object.entries(currentTemplate.fieldPositions).reduce((acc, [fieldId, position]) => {
    const pixelPosition = percentagesToPixels(position, displayedDimensions);
    return { ...acc, [fieldId]: pixelPosition };
  }, {});
};

Debug System

• Cache Bust Button: Force complete re-render with timestamp
• CSS Conflict Detection: Real-time CSS style inspection
• Comprehensive Debug: All-in-one positioning analysis
• Field Overlay Debug: Individual field positioning verification

Performance Optimizations

• Memoization: Prevented unnecessary recalculations
• GPU Acceleration: Transform-based positioning for smooth animations
• Efficient Re-renders: Optimized React component updates

🐛 Bug Fixes

• Fixed field positioning outside viewport issues
• Resolved coordinate system mismatches
• Corrected CSS transform interpretation
• Fixed mobile/desktop positioning inconsistencies
