Render a contemporary desert planetarium arranged around a shaded circular courtyard. Use a low rammed-earth ring building with deep recessed doorways, a clearly enclosed matte bronze projection dome and slender timber shade fins over pedestrian paths. Frame a landscape 4:3 exterior from a slightly elevated 28 mm viewpoint, showing the entry path in the foreground, courtyard in the middle and red sandstone mesas behind. Late afternoon sunlight creates long coherent shadows; scattered desert shrubs and three small adult visitors establish scale. Materials must show compacted earth layers, bronze seams and weathered timber, with beige, copper and dusty blue tones. Favor buildable geometry, accessible ground-level circulation and credible junctions. No floating roofs, warped columns, excessive glazing, large signage, brand logos or impossible interior views. Deliver one photoreal architectural bitmap, not a plan sheet or collage.
