Verification
The app is ready for deeper testing when you can:

- see the post in the feed and profile;
- like and comment on a post;
- search for users;

Troubleshooting
Image post fails
Check Storage rules, file URI handling, Firebase config files, and Functions logs if the upload triggers backend processing.
Feed does not update
Check Firestore indexes, query filters, feed documents, and whether the current user follows the author.
