   Resolved by #7.

   Pre-quantized MiniMax H3 INT8/ConvRot DiT checkpoints are supported. In MiniMaxH3SPUNETLoader, keep weight_dtype=default so ComfyUI reads the checkpoint's quantization metadata. The official INT8 video VAE should use the standard VAEDecode node.

   Validation on 2× NVIDIA L20 with the real minimax_h3_fl2va_pruned_int8_convrot.safetensors checkpoint passed SP2 parity: video relative error 1.199e-6, audio bit-exact. See the updated README and examples for model filenames and setup.
