Same seed, same prompt: only the slider changes

Every set uses one seed and one prompt; the only thing that changes is the slider strength (−1 / 0 / +1). Face, dress, pose and background hold steady. On the gym prompt, +1 adds size but keeps the muscle tone, because the slider works with your prompt rather than against it. Qwen-Image 2512, 20 steps, CFG 3.5, euler/simple.
