IrisArt Studio is a local-first desktop app that turns an ordinary eye photograph into print-ready iris artwork. You upload a photo, the app detects and centres the iris, crops it and applies a premium artistic preset; from there you fine-tune with live sliders and export to PNG, JPEG or PDF.
The app is deliberately an artwork tool only: it performs no biometric identification, iris matching or face recognition. Nothing is uploaded anywhere — all processing happens on your own machine.

03Engineering Notes
The image-processing layer is fully decoupled from the UI and can be tested without Qt.
The privacy constraint is an architectural decision: there are no network calls and no data leaves the machine.
