Slender Spiral Observation Ramp to a Viewing Deck

Slender Spiral Observation Ramp to a Viewing Deck: The tallest and narrowest of the pack's drums, a bare concrete shaft with a pedestrian-only ramp spiralling up its outside with daylight visible between the turns, an ink handrail ringing the viewing deck at the top, and an orange pedestrian figure partway up the climb. A stylized isometric neo-brutalist scene of raw board-formed concrete Brutalist architecture - flat unmixed colour with a heavy ink contour and no bevel, the hard offset shadow signature carried behind the entrance canopy or portico - delivered as a hero iso render on a transparent background plus the assembled model as GLB with the contour built as geometry.
