ReRoomAI 방식 사진 시안(image-to-image) 프롬프트 템플릿 — 참고용 단일 출처.
실제 조립은 client.build_reroom_prompt()가 수행한다(이 파일은 구조 문서·검수용).
근거: docs/analysis/reroomai-source.md §4 "보존/교체 명시적 분리" 4단 구조.

① 대상 + 스타일
Photorealistic professional photograph of this exhibition booth space at the KINTEX
convention center in South Korea, shown as if construction is complete.
Redesign it in this style: {style_prompt}.

② 보존 잠금 (고정 — 자연어 지시로 덮어쓰지 않음)
Keep the architectural shell exactly the same as the reference photo: the walls, floor,
ceiling, structural columns, ceiling trusses, aisle openings and the camera perspective
must all stay identical. Do not move, resize or re-frame the structure.

③ 교체 지정 (자연어 지시는 오직 이 파트에만 삽입)
Replace only the surfaces, furnishings, lighting, signage graphics, carpet and decor to
match the target style. Do not add real company logos or human faces.
Additional client direction (apply to the styling only): {instruction}

④ 사진 품질
Photorealistic tradeshow photography, {time_of_day} lighting, natural exhibition ambient
light with visible ceiling trusses, sharp focus, high detail. No people, no real brand logos
other than the specified signage text. It must look like a real construction-completion
documentation photo, not a 3D render.
