PDF Signing Tool

1. Signature Style Options:
   • Added 3 signature style options (Standard, Formal, Stamp)
   • Visual preview of each style
   • Interactive selection
2. PDF Preview with Movable Signature:
   • Added PDF preview container using PDF.js
   • Shows the uploaded PDF document
   • Interactive signature overlay that can be:
     • Dragged to any position
     • Resized by dragging the corner
     • Position updates the form fields automatically
3. Improved Positioning Workflow:
   • “Drag to Position” button activates the movable signature
   • Real-time position and size updates
   • Visual feedback during dragging/resizing
4. Enhanced User Experience:
   • Clear visual representation of where the signature will be placed
   • More intuitive positioning than just entering numbers
   • Responsive design maintained for all new elements

Implementation Notes:

1. You’ll need to add the PDF.js library (loaded dynamically in the code)
2. The signature overlay uses absolute positioning within the PDF preview
3. All original functionality remains intact – this just adds new features
4. The positioning inputs still work and sync with the visual positioning
