"""JANCTION Render examples 21 and 22: an alarm clock, a real 3D model from Poly Haven (CC0, "alarm_clock_01").

Reproduce: render_final(scene_url="https://render.janction.jp/samples/ex21_product_clock.py",
                        asset_urls=["polyhaven:alarm_clock_01"], preset="product",
                        orbit_elevation=25, orbit_distance=0.85)      # 4 studio shots, 1440x1440
           render_final(scene_url="https://render.janction.jp/samples/ex21_product_clock.py",
                        asset_urls=["polyhaven:alarm_clock_01"], preset="turntable",
                        orbit_elevation=25, orbit_distance=0.85)      # 360-degree MP4
No files to upload: the service fetches the model by name. The model is CC0 (https://polyhaven.com/a/alarm_clock_01).
The preset lights the studio and orbits the camera (25 degrees above, a little closer than the default); jr_assets.frame_camera() fits the model in the frame.
