Amlolife/pxgate — reverse-engineered prompt

Build me a simple polished desktop app called PXGate. I want it to help me open a folder of images, pick a client or job, and run an image review that shows useful details like file info, metadata, and any AI based analysis the app can do. It should feel like a real app, with an icon, clean screens, clear status messages, and simple buttons so a non technical user can import images, review results, and save or export what they need.

Please use the existing Python project as the source of truth and wire together the image analysis, ExifTool resources, client selection, and UI improvements that are already in the repo. Make it work locally on Windows and Mac, and include simple build scripts or instructions so I can create a distributable app. If something is unclear because the README is missing, make the safest practical choice and keep it simple. Look up current docs online if you need to.
