Create a modern, luxury mobile-first wedding invitation web app with smooth animations:
- Hero Section: Elegant background with couple names: "Ayaan & Fatima" with floral/gold borders.
- Story & Timeline Section: Scroll down to reveal the function details (Mehndi, Barat, Valima) with venue location and time.
- Interactive Scratch Card Section:
- A golden/silver canvas overlay that acts like a real scratch card.
- When the user scratches the screen (touch/mouse drag), the top layer gets erased (using HTML5 canvas touch events).
- Underneath the scratch layer, reveal: "Wedding Date: December 25, 2026 | Venue: Royal Palace Hall".
- Include a confetti celebration effect once 50% of the card is scratched.
- Mobile Optimized: Designed like an Instagram story / mobile viewport so it looks like an app when opened from
WhatsApp.
