Fresh ComfyUI process per cell; total physical-GPU memory sampled every 20 ms under the exclusive GPU lock.
`--highvram` is the no-model-offloading control; it is not `--gpu-only`.

GPU UUID: `GPU-27ff99d6-d77d-2226-a4b5-7a11b8ef6bdd`
Settings: 1024×1024, batch 1, 20 steps, Euler/simple, CFG 1.0, Flux guidance 3.5.
Source benchmark state: measurement complete, run `20260719T215033Z_1143248`. The benchmark used total physical-GPU memory because WSL did not expose per-process memory for compute rows.
