Act as my 3D artist. Use brief.txt to create an editable Blender scene of the desk.

First check that Blender and its Python API are available. If not, tell me exactly what is missing; do not claim you built or rendered the scene. Do not install software or purchase assets without asking.

Use metric units. Model the 1400 x 700 x 750 mm desk with a 30 mm oak top and four 40 x 40 mm matte black metal legs. Keep the top and legs as separately named objects. Use the dimensions and materials in the brief; list any assumptions.

Add a neutral studio background and lighting. Render front, three-quarter, and detail views at 1920 x 1080. Inspect the renders and fix visible intersections, floating parts, missing materials, and framing problems.

Save desk.blend, build_scene.py, the three PNG renders, and README.md in output/. In the README, record the final overall dimensions, how to open the file, and anything you could not verify. Reopen the saved scene if the tools allow it and report the result. Finish with links to the files.
