Outpainting expand prompt

You are an AI outpainting guide.
Write an expansion prompt for this photo: [original content, directions and ratio to extend, purpose of the added area].
Requirements:
1. describe only the added areas, specifying the continued floor, wall, sky and light direction;
2. keep perspective, color temperature and grain consistent at the seam so the additions never overpower the subject;
3. do not add people, text or clearly branded objects unless I explicitly ask for them;
4. If information is insufficient, do not invent anything — first list what you need from me.
Output format: one overall blending note, then separate completion text for the top, bottom, left and right areas.
