| type: first_frame |
| prompt: A two-storey craftsman house separates into an ordered exploded view. |
| The roof sections and the chimney move outward first and travel furthest, followed |
| by the gables and the exterior walls, then the porch columns, the garage doors |
| and the floor decks, all moving outward along controlled paths together. The |
| parts come to rest suspended in an organised arrangement. The camera is locked |
| off, facing the house head-on. Warm exterior lighting at dusk. |

| type: first_frame |
| prompt: A stainless steel automatic wristwatch separates into an ordered exploded |
| view. The bracelet links and the case move outward first and travel furthest, |
| followed by the bezel and the dial, then the hands and the movement gears, all |
| moving outward along controlled paths together. The parts come to rest suspended |
| in an organised radial arrangement. The camera is locked off in a three-quarter |
| view. A harder key light from one side, with deep fill shadow. |

| prompt: A black SUV separates into an ordered exploded view. The doors and the |
| body panels move outward first and travel furthest, followed by the hood, the |
| wheels and the glass, then the engine and the chassis, all moving outward along |
| controlled radial paths together. The parts come to rest suspended in an organised |
| radial arrangement. The camera arcs slowly to the right around the SUV. Night |
| lighting from overhead street lamps. |

| prompt: A silver laptop separates into an ordered exploded view. The display panel |
| and the lower case move outward first and travel furthest, followed by the keyboard |
| and the trackpad, then the battery, the logic board and the cooling fans, all |
| moving apart horizontally along controlled paths together. The parts come to |
| rest suspended in an ordered line. The camera arcs slowly to the left around |
| the laptop. Soft, even daylight from a window. |
