What it would take to fix

StockX handles most images well but minor gaps remain. Filtrate's /v1/process covers the edge cases: any image that slips through without full EXIF stripping gets cleaned up before it reaches the CDN. The integration adds one POST call to the upload path and covers 100% of images uniformly.
