MiniMax H3 I2V Javawock Pack

Summary

Same-day MiniMax H3 first/last-frame image-to-video workflow from the javawock7618 pack. This is the missing local sibling from the pack and the cleanest new add if you want the I2V lane.

Developer notes

• The source README describes this as the First-Last-Frame workflow.
• It uses the same INT8 / Sol-Attn / SLA-Attention / Spectrum stack as the rest of the pack.
• The I2V graph integrates native Extend and the MiniMax-H3 latent upscaler for faster high-resolution generation.

Our notes

• Good practical add for a MiniMax H3 local workflow set.
• Not as directly interesting as the face-refine or reference-retention lanes, but still useful if you want a first-frame path with the pack's newer stack.
• Still a tight fit on an RTX 3070 with 8 GB VRAM, so treat it as a serious test target rather than a casual throwaway graph.
