Zora IPFS upload CID differs from other IPFS services #527
Description
I wanted to pin Coin images and metadata JSON files to additional IPFS services for redundancy, but I am finding that the Zora IPFS upload gives a different CID for the same content.
Below is a minimal reproduction script for Filebase as an alternative provider. I have additionally verified with Pinata and bgipfs.com (which return the same CID as Filebase).
/**
* Zora IPFS Upload Bug Report - Proof of Concept
*
* This script demonstrates that Zora's IPFS upload endpoint behaves differently
* from other IPFS services when using the same multipart form data approach.
*
* Issue: Zora produces different CIDs and file sizes compared to other IPFS services
* for the same uploaded content.
