  "prompt": "Create ONE single-frame, photorealistic commercial product photo. IMPORTANT: Use the uploaded product image as the exact packaging reference (do not alter logo, Korean text, label layout, colors, or sachet/box design).\n\nSCENE / LOCATION: A clean premium home-kitchen tabletop scene (not a studio pour-action shot). Background: softly blurred modern kitchen (neutral, tidy, no readable brand text). Table surface: clean light wood or light stone.\n\nCOMPOSITION: The hero is a clear drinking glass filled with water to about 2/3 height, placed near the center or slightly right of center. On the table next to the glass, place the matching pastel-pink product box and ONE pink stick sachet from the same product set. The sachet must be the SAME product as the box (matching branding and Korean text). The sachet should be unopened and lying neatly (or lightly leaning against the box). No other pouches or different products anywhere.\n\nLIGHTING: Soft natural daylight from a side window, high-key and clean. Gentle shadow under the glass and product. Clean reflections on the glass. Premium Korean supplement advertising aesthetic, minimalist negative space.\n\nFOCUS: Keep the glass and the product box/sachet in clear focus (sharp enough to recognize the correct branding; Korean text should not become gibberish). Background kitchen remains softly blurred.\n\nABSOLUTE CONSTRAINTS:\n- Do NOT show any pouring, mixing, powder clouds, powder residue, torn sachet edges, or powder floating in the water.\n- Do NOT show a hand or person.\n- Do NOT introduce any extra sachets or different pouches. Exactly ONE box + ONE stick sachet + ONE glass.\n\nSTRICT OUTPUT RULES: single image only, single composition only, one camera view. Do NOT create a collage, grid, diptych, triptych, contact sheet, storyboard, or multiple frames. No borders, no dividers, no white gutters.",
