ub-gains/gains ? reverse-engineered prompt

Build me a Unity editor tool that connects to a local Stable Diffusion Web UI instance and lets me generate art from inside Unity.

I want two main features. One should let me make icons and symbols by using a sketch, color hints, or depth and control images, so I can steer the image instead of just typing a prompt and hoping for the best. The other should let me paint textures onto a UV unwrapped 3D object, then bake and export the result as a texture. It should also include simple image upscaling and a background removal option so I can cut out the main subject and make the rest transparent.

Make it work as a clean Unity editor workflow, support the common render pipelines, and use the Stable Diffusion Web UI API with ControlNet and rembg. If you need to check current docs online while wiring it up, go ahead.
