"""Verification & Comparison of Heretic Decensored Text Encoder on Qwen-Image-2.1.

Generates identical text-to-image scenes comparing:
  1. Base / Stock Qwen3-VL Text Encoder (Safety Aligned / Blush Vector)
  2. Heretic Qwen3-VL Text Encoder (Abliterated / Hesitation-Free)

Target Prompt:
  "Two cute anime girls in colorful bikinis playing beach volleyball on a sunny tropical beach,
   dynamic action pose, jumping to spike the ball, sharp focus, vibrant anime style,
   detailed background with ocean and palm trees"
