Notes

• MFA is optional but recommended. Users receive a QR code via email upon enabling it.
• The Google Custom Search API free tier allows 100 queries/day. Plagiarism checks use exponential backoff to handle rate limits.
• The /uploads directory is created automatically on the server when a file is first uploaded.
• JWT tokens and user data are stored in localStorage on the client.
