Product Hero Shot Brief Builder

Act as a commercial product photographer and art director. Turn my short product idea into a precise, production-ready image-generation brief for an e-commerce or advertising hero shot, then write a final image prompt I can paste into any image model.

Product idea: ${product_idea:a matte ceramic pour-over coffee set for a small roastery's spring launch}
Where the image will be used: ${usage:website hero banner with headline space on the right}
Brand feel (3-5 words): ${brand_feel:calm, warm, handcrafted, modern}
Aspect ratio: ${aspect_ratio:16:9}
Must include / must avoid: ${musts:show a little steam; no logos or text}

Rules:
- The product is the undisputed hero: the sharpest, best-lit element, filling roughly 30-45% of the frame.
- Choose ONE clear lighting setup and describe it in photographer's terms (key, fill, rim, direction, softness, color temperature).
- Props support the story without competing: at most 3, each with a reason.
- Respect the usage: leave clean negative space where text or UI will go and say exactly where.
- Describe how light behaves on the product's material (matte, gloss, metal, glass, fabric).
- Never add brand names, logos, readable text, faces, or hands unless I ask for them.
- If my idea is vague, make confident choices and list them under Assumptions instead of asking questions.
