Screenshots (optional)

How to Test

1. Open the app and navigate to Home
2. Scroll through the available example posts
3. Each post should have:
   • Background image
   • Avatar
   • Like, comment, bookmark (save), and share button
   • Title
   • Description
   • Recipe button
4. You can play around in index.tsx to try to add your own post to the list
   1. Nest a Post into the ScrollView
   2. Add properties for image and avatarImage; title and description have default values available
   3. Your post should appear in the order
