PolyfaceMesh and PolygonMesh were wireframe-only. They now render with the same flat-color solid fill as Face3D entities. - Add fill_tris: Vec<[f32;3]> to TruckEntity and WireModel - PolyfaceMesh: fan-triangulate each face into fill_tris - PolygonMesh: triangulate each grid quad into fill_tris - tessellate.rs Lines branch: apply world_offset to fill_tris - Face3DGpu::from_wires: collect fill_tris from all wires in addition to Face3D key_vertices quads - upload_face3d: pass all_wires so fill_tris are batched into one draw call
