Godot @tool render scene that takes a textured 3D model and produces 2D sprites at 1024/256/64 from 4 cardinal directions with outlines applied at working resolution. Camera at "the angle" (-72.5deg ortho). Includes two POC wall models with Nano Banana textures, CLI wrapper script with headless import step, and .uid files added to gitignore.
