Draft: Social Video Sharing Platform (Like Facebook/YouTube)

Build an online social platform where users can register, upload videos, and watch others' videos. The application should support the following core features:

- User registration and authentication
- Video upload functionality (with file size/type validation)
- Video streaming and playback
- User profiles (with list of uploaded videos)
- Feed or explore page for trending/new videos
- Basic social interactions (likes, comments, shares)
- Responsive design for both desktop and mobile

Optional/Stretch Features:
- Live streaming
- Video recommendations
- Private messaging
- Playlists and subscriptions

The overall goal is to create a platform similar to Facebook's video feature or YouTube, focusing first on core video upload and viewing functionality.
