xandergos/terrain-diffusion — reverse-engineered prompt

Build me a Python project that recreates this terrain diffusion tool for procedural world generation. I want to be able to run it locally and generate realistic terrain from either a random seed or a rough coarse map, then explore the world in a simple two panel viewer where I can click on the coarse map and see a detailed shaded relief result, plus an option to view climate like temperature.

Please also include the basic command line flow to start an explore mode, run a small local API for querying elevation and climate, convert an Azgaar Fantasy Map JSON export into conditioning TIFF files, and export a high resolution GeoTIFF from those inputs. It should support deterministic results from seeds and work on CPU, but use an NVIDIA GPU if available.

If there is a self contained demo for the infinite panorama idea, wire that up too so I can run it and get an output image. Keep setup straightforward, document how to install and run everything, and look up current docs online if you need to.
