Illuminated staircase descends centerline through cavern floor, casting warm reflections on textured surfaces. Contrasting shadows deepen recessed architecture against luminous core. Overhead limestone formations frame composition. Render employs high dynamic range tonal compression from near-black shadows to intense orange highlights.
