碎瓷拼贴：trencadís 的曲面表皮

Design an undulating architectural surface in the manner of Antoni Gaudí clad entirely in trencadís — broken ceramic tile mosaic where irregular shards of glazed pottery and glass are set by hand to follow a doubly curved form no flat tile could cover. Compose a serpentine parapet bench snaking across a terrace, fragments in cobalt, ochre, white and bottle green, mortar joints visible between shards, the pattern shifting from figurative to abstract along its length, bright Mediterranean sun making the glaze flash, low three-quarter view along the curve, 28mm lens, architectural photography, ultra photorealistic, 8K
