Developer notes

• The source README describes this as the First-Last-Frame workflow.
• It keeps the pack's INT8 / Sol-Attn / SLA-Attention / Spectrum stack and the integrated latent upscaler path.
• The bundle also adds Fun ControlNet Union support for V2V-style control-video guidance.

Our notes

• Best new MiniMax H3 I2V import from today if you want the newer pack version.
• Still a heavy workflow for an RTX 3070 with 8 GB VRAM, so this is a test target rather than a casual run.
• Useful comparison point against the older MiniMax H3 and LTX first-frame graphs already in the repo.
