Tiny Wan2.1 VSA T2V 14B 720P Debug Pipeline

This is a randomly initialized, tiny WanPipeline fixture for FastVideo/Wan2.1-VSA-T2V-14B-720P-Diffusers. FastVideo Wan2.1 VSA 14B 720P text-to-video layout represented as a tiny Diffusers WanPipeline artifact for FastVideo VideoGenerator and VIDEO_SPARSE_ATTN load-path debugging. The saved transformer weights include FastVideo VSA to_gate_compress tensors, which are not emitted by Diffusers.

It is intended for fast load-path and inference-control debugging only. It is not trained and should not be used for generation quality evaluation.
