New node that modifies prompts based on Z-Image structure:
- Takes input prompt and LLM model
- 6 section instruction inputs: subject, clothing, pose, environment, lighting, camera
- Two processing modes: Single Pass (faster) and Section by Section (precise)
- Temperature control for LLM creativity
- Optional Instagram caption generation (3 styles)
- Text-only LLM calls (no image required)

Phase 2 will add SID_LLM_Local_Text support.
