INPUTS TO COLLECT -...
Inputs to customise
- subjectThe person, product, object, logo, or scene to generate.
- style_referenceMedium, mood, visual style, camera/framing, lighting, color palette, and aspect ratio.
- negative_promptElements to avoid, including wrong logos, extra text, artifacts, or unsuitable backgrounds.
Quality checks

- Galaxy background has named visual attributes (spiral arms, violet-gold palette, star clusters) for accurate rendering.
