+    Entity-Level Image Generation (EliGen) conditioning node for Qwen Image model.
+
+    Allows specifying different prompts for different spatial regions using masks.
+    Each entity (mask + prompt pair) will only influence its masked region through
+    spatial attention masking.
+
+    Features:
+    - Supports up to 8 entities per generation
+    - Spatial attention masks prevent cross-entity contamination
+    - Separate RoPE embeddings per entity (research-accurate)
+    - Falls back to standard generation if no entities provided
+
+    Usage:
+    1. Create spatial masks using LoadImageMask (white=entity, black=background)
+    2. Use 'red', 'green', or 'blue' channel (NOT 'alpha' - it gets inverted)
+    3. Provide entity-specific prompts for each masked region
