Half-Round Stair Drum Cantilevered off an Office Slab

Half-Round Stair Drum Cantilevered off an Office Slab: A cream office slab gridded with cyan and yellow windows, a half-round stair drum bonded to its side face and overrunning the roofline with its own ink cap, nine cyan stair windows climbing the drum, the whole thing touching ground at one point on a single ink column with a pave landing, and an orange pedestrian figure waiting at its base. 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.
