JANCTION Render（MCP サーバー https://render.janction.jp/mcp）で、この作例を描いて: render_preview(scene_url="https://render.janction.jp/samples/ex25_isometric_office.py")。そのあと、私の題材に合わせて色・形・カメラを変える案を出して。仕上げの前に確認して。

"""JANCTION Render example 25: an isometric office corner with an orthographic camera (one still).
Reproduce: render_final(scene_url="https://render.janction.jp/samples/ex25_isometric_office.py",
width=1200, height=1200, samples=128, environment="overcast")
Two walls, a floor, a desk with a monitor, a chair, a shelf, plants and a bright window, all from cubes and
cylinders. The camera is orthographic at the classic isometric angles (54.7 and 45 degrees).
