Build a prompt for product imagery

Build a prompt for a generated product image.

**First, the boundary.** Before anything else, tell me which of these must be photographed rather than generated:
- The product itself, if a customer will judge color, texture, or size from it
- Anything with text, a logo, or a label
- Anything a claim depends on — size comparisons, included contents, condition

*Generated imagery that misrepresents a product causes returns and disputes. Say this plainly rather than producing a prompt for something that should be a photo.*

Then, for what can reasonably be generated — background, scene, mood, lifestyle context:
1. Medium and aspect, stated twice.
2. **Locked attributes** — exact color, material, finish, and proportions of the product. These must not drift.
3. Composition: where the product sits, how much frame it occupies, negative space for text if the placement needs it.
4. Camera and lighting appropriate to the category.
5. Props and setting, matched to the brand tone.
6. Negatives — especially text, logos, and watermarks, which generators insert uninvited.

Finally:
- What to verify in the output against the real product, as a checklist.
- Where a real photo composited onto a generated background would be safer than full generation.
