Rani-ki-Vav is an 11th-century stepwell in Patan, Gujarat — an inverted temple of water that descends seven storeys into the earth. Commissioned by Queen Udayamati in memory of her husband King Bhima I, its carved sandstone walls drop into deep geometric shadow, lined with over 500 principal sculptures of the Dashavatara, apsaras, and nagakanyas.

This design system translates that subterranean descent into interface: the ground is not lit stone but the shadowed sandstone face, vertical rhythm organises the page like stacked step-terraces, and ochre carving emerges from deep recessed dark. It is austere, weathered, and tactile — carved relief, not painted gold.
