Twin-Towered Served-and-Servant Wings with Plum Sky-Bridges

Twin-Towered Served-and-Servant Wings with Plum Sky-Bridges: A main slab flanked by two narrow stair and duct towers standing physically detached from it, plum sky-bridges linking the towers back to the slab at two levels, cyan and yellow window bands lighting the gap between, and an orange car parked at the entrance. 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.
