Use case: ads-marketing. A premium full-bleed product group-buy opening announcement for a social feed. Fixed composition: oversized opening headline, one product hero, exact product name and period, optional price and benefit, profile-link call to action. The mood changes lighting and colors, never the output type or layout family. Fill the canvas edge to edge. Keep all text clean and readable at phone size, with generous edge padding. Adapt spacing to the selected ratio.
Product photo input: "【商品写真】". A text filename alone is not an attachment. If one product image is attached, use that exact product as the immutable source: preserve silhouette, proportions, colors, surface details and existing label letters verbatim. Do not repaint, rename, replace packaging, duplicate products or cover identifying details. Change only background, positioning and scale. If no image is attached, create one original fictional product suggested by the product name, with no lettering or logos on its surface; avoid recognizable real product designs. Never invent a real brand mark. No people.
Product name: "【商品名】". Period: "【期間】". Group-buy price: "【共同購入価格】". Original price: "【通常価格】". Benefit: "【特典】". Mood: "【雰囲気】".
Mood options, in order: 清潔な白いスタジオ / 温かい暮らしの雰囲気 / 鮮やかなセールカラー. First means soft white seamless studio with restrained dark type and accents from the product. Second means warm sunlight, cream or apricot and tactile plain surfaces; do not add food or ingredients. Third means bold coral, magenta or cobalt flat color planes with crisp high-contrast typography. Blank mood defaults to the second option. The product retains its actual color in every mood.
Print only these texts, once each: "共同購入 OPEN" (largest), the exact product name, the exact period, and "リンクはプロフィールへ". When the group-buy price is nonempty, print "共同購入価格" followed by the exact supplied amount and currency. If blank, omit that entire line and reclaim space. Show the exact original price with one clean strikethrough only when BOTH price fields are nonempty. Otherwise omit original price entirely. Print the exact benefit as one short clearly separated line only when nonempty. Empty optional fields never appear as labels, dashes, placeholders or made-up offers.
Use professional photographic product lighting with editorial typography. No extra slogans, discount rates, guessed prices, invented deadlines, lowest-price or ranking claims, awards, reviews or scarcity. Never infer ingredients or health, treatment or weight-loss effects; if the product is a health supplement, omit all efficacy claims, even if requested in a benefit. Cosmetics must not receive fabricated ingredient or efficacy claims. Do not draw third-party logos or recognizable trademark designs; source products must be authorized and free of third-party marks.
Preserve input spelling, spaces, punctuation, digits and currency exactly. Do not add weekdays or recalculate offers. Before returning compare every name character, date digit, amount and benefit quantity against the inputs and repair any errors. Also compare photographed product shape, color and label lettering with the source. Return one ready-to-post announcement image.
