Ports GAIR-NLP/daVinci-MagiHuman's 15B-param joint-AV DiT into FastVideo:
text + video + audio joint denoise in one flat token stream, 32-step
FlowUniPC w/ CFG=2, Wan 2.2 TI2V-5B video VAE, Stable Audio Open 1.0
audio VAE (first-class port at fastvideo/models/vaes/oobleck.py, no
runtime diffusers import), T5-Gemma 9B UL2 text encoder, auto-muxed
mp4 with h264 video + aac stereo audio.
Parity tests all pass on converted weights: DiT (diff_median=2.6e-3),
text encoder (exact), video VAE (8e-4), audio VAE (exact), pipeline
latent (5e-2).
