实际提示词

ONE 3:4 vertical social COVER POSTER for original AI art. ONE open deep-PLUM hardback BOOK on an ivory pedestal. Blank ivory page block on right turns into one continuous miniature STAIRCASE ascending toward back, layered page edges and APRICOT-ORANGE tread accents clearly visible; left pages remain flat and blank. Full book and connected stair silhouette inside lower two-thirds, physical crafted paper art with coherent contact shadow and single soft side light. Warm-ivory backdrop, generous title safety margin. Exact large dark-plum simplified Chinese title ONCE at top in TWO lines: '书里藏着' then '一段楼梯'. Exact small footer ONCE bottom: 'AI创作 · 杨老师玩AI'. Title never overlaps sculpture, thumbnail clear, no other text, numbers, flying pages, book names, logos or collage.
