SnapPic is a Flask-based web application that allows users to temporarily share photos. Each uploaded image is displayed for 5 seconds, then fades out over 10 seconds before being automatically deleted.

• ✏️ Add short comments (max 100 chars)
• ⏱️ Images automatically expire after 15 seconds (5s visible + 10s fade)
• 📱 Responsive design works on mobile and desktop
• ⚡ Progressive Web App (PWA) support
• 🔄 Auto-refreshing gallery updates every 2 seconds
• 🔒 Secure file upload handling

• Backend: Python Flask
• Frontend: Vanilla HTML/CSS/JavaScript
• Storage: Local filesystem for images, JSON for metadata
• PWA: Service Worker + Web Manifest
