Describe a scene — it renders on the GPU and downloads as a PNG.

Timing: roughly 23s fixed + 2s per step — so 28 steps
≈ 78s, 12 steps ≈ 47s. HiDream always renders about 1 megapixel, so the aspect
ratio does not change speed; steps are the only speed control.
Images render one at a time, so concurrent requests queue.
