Original 320 × 70 × 60 m light cruiser reconstructed from sheet.jpg, metres, +Z nose, +Y up, +X left; source-authoring frame converted explicitly at export.
Targets: front port three-quarter hero, orthographic side, rear engine block, close plating/hangar, plain clay; dark blue-black void, white key and cool fill.
Outputs: light-cruiser.glb, build_light-cruiser.py, final.png, paints.png, side.png, clay.png, nodes.json, six-line NOTES.md. Extra validation captures live under qa/.
Budgets: 80–200k triangles, ≤9 materials, ≤12 MB GLB; colour/normal ≤1024, ORM ≤512; tiled plating with metre-scale UVs and geometry window/vent trims. One GPU job at a time from this task.
Paint base factor [0.60,0.61,0.62], neutral baked texture; four traversing twin turrets with elevating guns, separate origins and sockets. No text or insignia.
