Original 1K diffuse, OpenGL normal and roughness JPG asset files are used.
Unity imports normals as normal maps, uses metre-scaled UVs (2m repeat),
applies existing district vertex colours, and blends within work zone C01.
No website preview renders or third-party game assets are bundled.

Drain grates, inspection hatch and flashing are original NOVA geometry.

Wood grain is mixed with existing timber; roof colour is desaturated in the
shader to preserve the established district palette. Hardware, window seals,
rail fixings, drainage receivers and equipment anchors are original geometry.
