6It does four things in order and prints everything to stdout in
7copy-paste-friendly markdown/table form:
8
91. **System header** — version, time, OS, detected GPU.
102. **wgpu adapter info** — backend (Vulkan/Metal/DX12/GL), device name, vendor,
11   relevant limits.
123. **vello vs direct GPU spike** — for N ∈ {25K, 50K, 100K, 200K, 500K, 1M}. It
13   measures ms/frame for each and the factor, and evaluates the SDD's criterion:
14   ≥5× at 500K → PASS; below → ABORT.
154. **Direct-GPU scaling alone** — for N ∈ {100K, 500K, 1M, 2M, 5M, 10M}. It
16   measures ms/frame, equivalent fps and Mprim/s, and evaluates the 60 fps @ 1M
17   goal.
185. **Visual verification PNGs** — it exports two files to the cwd:
19   `bench_vello_100k.png` and `bench_directo_100k.png`. The shape of the dot sky
20   must match between the two (deterministic LCG).
