🔒 Security Notes

• Processing happens in browser → no leak to backend unless you pass it.
• Disable PDF rendering to avoid malicious scripts.
• Do not trust metadata blindly — always validate server-side.

🧭 Limitations

• Cannot extract content text (this is metadata-only)
• Some PDFs may not include metadata
• Encrypted PDFs will fail to parse
