I'll recreate this interactive Mother's Day card as a Next.js application. Let's build it with modern React components while preserving all the functionality and design from the original HTML.

This Next.js application recreates the interactive Mother's Day card from the HTML file. Here's what I've done:

1. Modern Implementation: Used React with Next.js App Router and client-side components
2. Animation Library: Added Framer Motion for smooth animations
3. Responsive Design: Maintained the original dimensions and styling
4. Image Optimization: Used Next.js Image component for better performance
5. Tailwind CSS: Implemented custom utilities to match the original CSS effects

The card works exactly like the original:

• Click on the envelope to open it
• The envelope flap animates open
• The card slides out with the Mother's Day message
• The envelope disappears after the card is fully revealed

The message content is preserved in Spanish, keeping the original sentiment from Walter to his sisters.
