MiniMax H3 lip-sync workflow gains automatic long-video chaining and VRAM optimizations

A ComfyUI workflow for MiniMax H3 lip-sync generation now supports automatic long-video chaining, allowing unattended production of extended synchronized outputs, alongside speed and VRAM usage improvements. The update addresses a practical gap in H3's handling of long-form lip-sync sequences for production workflows. The workflow and nodes are shared publicly.
