阶梯状立面与大字：美术馆作为都市招牌

Design a downtown art museum in the manner of Robert Venturi's Seattle Art Museum — a limestone facade stepping up a steep street with the museum's name cut in very large letters into the stone itself, treating signage as architecture rather than as an addition. Compose a fluted pale limestone elevation with terracotta and granite banding, oversized incised lettering running across the facade, a broad flight of steps climbing beside it, an arched entrance at the low end, city buildings crowding above, bright cool daylight, low oblique view up the street, 24mm lens, architectural photography, ultra photorealistic, 8K
