dave0x1/Boldcraft ? reverse-engineered prompt

Build me a simple artist portfolio site for Boldcraft with two parts, a public gallery and a private owner area.

The public side should feel polished and visual, with a clean gallery for artwork, image pages or lightbox viewing, and a way to browse pieces nicely on desktop and mobile. The owner side should let me sign in, upload new images, manage existing work, and organize the gallery without touching code.

I also need a backend that handles image uploads, basic processing, and authentication, with storage set up for cloud image hosting. Please make it a working monorepo with the frontend and backend separated, and wire everything together so I can run each part locally and start using it right away. If you need to check current docs for anything, go ahead and look it up online.
