Layout: The Golden Ratio (Fibonacci Spiral).

[COORDINATE MAPPING]
- The Origin (The tight center of the spiral): A glowing ancient artifact on a pedestal. Focus is razor-sharp here.
- The First Arc: A sweeping, curved stone staircase wrapping around the pedestal.
- The Outer Arc: Massive gothic cathedral windows bending to follow the curve of the spiral.
- The Negative Space: Dust motes caught in light rays, following the mathematical curve downward.

<instruction>
Render the scene. Every physical element (stairs, light, architecture) MUST bend to obey the geometry of the Fibonacci spiral. Do not draw the literal spiral lines; build the environment in that shape.
