On DGX Spark the 128GB is unified memory shared with the host CPU, so all

`--mem-fraction-static 0.95`. The SM121 recipe is not yet validated on that

- **H200 (SM90)**: BF16 and FP8 only — the card has no FP4 tensor cores, so the
NVFP4 checkpoint's MLP would fall back to the Marlin W4A16 weight-only path
and its cell is greyed out. The H200 recipes use 32768-token prefill chunks
