Class LTXAddVideoICLoRAGuideAdvanced

iclora.py:261–466

Extended IC-LoRA guide node with per-guide attention strength control. Same as LTXAddVideoICLoRAGuide, but adds attention_strength and attention_mask inputs to control how strongly this guide's conditioning influences generation via self-attention.
