橢圓天窗下的混凝土摺梯

An empty exposed-concrete stairwell spirals gently around an oval opening, one elliptical skylight projects bright light onto the lowest landing. Architectural photograph with clean verticals, believable railing and step spacing, warm gray concrete pores, no people or furniture. Square 1:1 standalone finished image. No text, logos, watermark, border, multi-panel layout or contact sheet.

空曠清水混凝土樓梯間圍繞橢圓開口緩緩轉折，一處橢圓天窗把亮光投在最低的平臺上。建築攝影，垂直線端正，欄杆與臺階間距合理，暖灰混凝土孔隙可見，沒有人物或傢俱。 方形1:1獨立完整成圖。不要文字、標誌、水印、邊框、多格排版或聯絡表。
