LTX-2.4 Prompt Enhancer

Standalone Gemma-4 (google/gemma-4-E2B-it) prompt enhancer for LTX-2.4. Expands a short user prompt into a detailed audio-visual caption in the model's training-caption style, exactly replicating diffusers' LTX2Pipeline.enhance_prompt (system prompt by mode, greedy decoding with no_repeat_ngram_size=3).

Kept as a separate ZeroGPU Space so the enhancer (and its torchvision dependency) stays off the main 22B video Space's memory budget — the LTX-2.4 video demos call this over gradio_client. Add a first-frame image to enhance for image-to-video.
