AXIOM A31 // 0xAA DREAM SEQUENCE

The dreamer enters a cathedral with no statues and no altar, only aisles that remember motion before it happens. Footsteps appear ahead as orange pressure rings, then travel backward across the stone and climb the walls as violet sound-arches. Each arch contains a different possible route through the building, and the routes braid together into a vaulted geometry that continually rewrites the floor plan. The artifact should feel architectural and prophetic: recursive arches, echo pulses, vanishing-point corridors, thin signal rain, and a central nave that dilates like an aperture listening for the next step.
