  "instruction": "Build a Geometry Nodes-driven pipeline from `/home/user/Desktop/bricks.csv`: create `BrickPoints`, instance `Brick` on it, drive color from `hue`, animate a turntable, render frames 1-30 to `/home/user/Desktop/output/frame_0001.png` through `/home/user/Desktop/output/frame_0030.png`, and save `/home/user/Desktop/answer.blend`. ## Requirements 1. `/home/user/Desktop/answer.blend` exists and opens. 2. `/home/user/Desktop/output/frame_0001.png` .. `/home/user/Desktop/output/frame_0030.png` all exist. 3. `BrickPoints` is a MESH object with exactly 100 vertices. 4. `BrickPoints` carries a POINT-domain FLOAT attribute named `hue`. 5. `Brick` has material `Mat_Brick` with ShaderNodeAttribute (attribute_name='hue'), a ShaderNodeValToRGB ColorRamp, and a ShaderNodeBsdfPrincipled node. 6. `TurnPivot` (or the Camera) is animated on rotation_z such that the camera's cumulative XY polar sweep across frames 1..30, or the pivot's z-rotation delta from frame 1 to frame 30, is >= pi radians. 7. Launch Blender by running `blender` from a terminal. At the start of the task, use `/opt/blender/blender` for Blender command-line or background runs.\n\nSilhouette (alpha > 0.5 pixel count) varies across frames: max/min ratio >= 1.1 over the 30 frames. 8. Frame 15 shows color variation from the hue-driven ramp: the R-channel standard deviation over alpha>0.5 pixels is >= 0.1, and the G-channel stddev is >= 0.1.",
