Should real-world models have realistic sizes, assuming meter units

The glTF spec says that linear distances have meter units. It looks like some models (for example BoomBox) do not use meter units. It looks like it's off by maybe a factor 10.

Start with the glTF specification's meter-unit requirement and inspect the BoomBox sample asset mentioned in the issue. Compare the asset's reported dimensions with realistic meter-scale expectations, then check whether other sample models show the same discrepancy. Done means the affected assets and the required resolution are identified and recorded.
