 `llimphi-3d` is a **3D engine** on the same `wgpu`: it composes voxels (a GPU ray-march) and triangle meshes in one shared depth pass, with a keyframed cinema camera. It mounts into the ordinary 2D `View` tree through the GPU paint node (`set_viewport` + scissor), so a 3D viewport can live in a panel next to regular widgets — no second window, same Elm loop.
