AI-KSK ComfyUI workflow: MiniMax H3 LightX2V 4 Step FL2VA.

This workflow is the LightX2V 4-step first-last-frame route. It pairs the MiniMax H3 FL2VA INT8 model with the official LightX2V turbo 4-step LoRA (768p ComfyUI bf16 build) on a 4-step schedule, for the fastest first/last-frame generation in the LightX2V series.

Main features:
- LightX2V turbo 4-step LoRA (768p ComfyUI bf16 build)
- MiniMax H3 FL2VA INT8 model with Qwen3-VL encoder
- First and last frame input plus text prompt
- 4-step simple schedule for very fast iteration
- Audio-conditioned MiniMax H3 MP4 output

Suggested workflow:
Use this route to screen first/last-frame shots quickly. Keep both endpoint frames consistent and use it before the 8-step version when judging camera motion or blocking.
