    "Nex: one DGX Spark, BF16, eager execution, no speculation, 131,072 configured context, temperature 0.6 and no request output-token cap. Requested xhigh falls through to normal thinking in its native template; it is not a distinct supported effort.",
    "Ling is the earlier two-Spark FP8 run: temperature 0.7, thinking enabled, xhigh requested and a 120,000-token cap. Different hardware, precision, sampling and cap policy make this a visual comparison\u2014not a controlled speed contest.",
    "The Nex repair adds only const lampSprites = []; and let waterMesh = null;. The saved verification exercised Day, Dusk, Night, Rotate, Petals and Reset. This is a ten-second render excerpt. Full-benchmark scores are separate and are not ranked here.",
    "The Ling output is the same saved generation used in both the Qwen vs Ling and Nex vs Ling comparisons, not an independent second sample."
