🎅 Secret Santa Web Application

A festive web application for Secret Santa gift exchanges with encrypted assignment links. Note: the giver/receiver assignment and link generation is done separately; this val only reveals who the giver is matched with. See Technical Details for more.

• 🎄 Splashy Christmas-themed UI with falling snowflakes and festive animations
• 🔐 Encrypted assignment links for secure Secret Santa assignments
• 🎁 Interactive gift reveal - click the gift box to discover your assignment
• 📱 Responsive design that works on all devices
• ✨ Celebration effects when the assignment is revealed

1. Welcome Page (/) - Shows a festive landing page for users without a valid token
2. Assignment Page (/{encrypted-token}) - Decrypts the token and shows:
   • A personalized greeting to the giver
   • An interactive gift box that reveals the receiver when clicked
   • Festive animations and celebration effects

The giver/receiver pairs and encrypted link can be generated via this code or the moral equivalent.

The decrypted token should contain:

{
  "giver": "John Doe",
  "receiver": "Jane Smith"
}
