**IMAGE PROMPT FOR: "Before Meaning: Hemisphere Filled With Cold Sky"**

A monumental, seamless hemisphere—40 meters in diameter—envelops the viewer. The camera is placed inside, looking sharply up and slightly oblique, aligned with a power-point intersection of the frame’s thirds; the oculus is near the upper left, never centered, its crisp disk edged with a micro-chamfer of cast concrete, appearing as a cold black void rimmed by an electric-blue corona. The curvature is so immense it verges on spatial ambiguity: the lower dome dissolves into indigo-black, the springing lost in total shadow, with no visible seam between wall and sky.  

**Surface:** The dome’s interior is matte, cool white lime-plaster, dusted in places with crushed ultramarine chalk; subtle hairline cracks and crazing track across the surface, their fine filaments catching haloed highlights as the light shaft passes. These crack networks fade in and out of prominence, some brightening to cyan under the grazing light, others lost to shadow. Where the oculus shaft bends across the dome, the curvature compresses under a banded meniscus of dense, lensing lapis air—a subtle optical distortion that makes the dome surface seem to flatten just beneath the light, inducing a visual tension between depth and flatness.

**Light:** Sole illumination comes from the five-meter-wide oculus. Above, thin clouds rush past, causing pulses of corona brightness and flickers of electric-blue spokes that radiate from the rim and refract through clusters of *acoustic frost*—needle-thin ice crystals trembling silently, each shimmering cyan as they catch the shaft, lengths modulating with the hum of the space (17 Hz resonance, visible as faint ripples in the air). The light pours downward as a directed, volumetric shaft: cool, columnar, hard-edged at the top, fanning imperceptibly, diffused by micron-scale dust that becomes visible as a swirling milk-glass haze only where backlit. This shaft actively models the dome’s surfa
