Original GLB 5,016,448 bytes; optimized basic.glb 686,700 bytes; 2 triangles.
Runtime floor footprint expanded from 6m to 120m, with texture repetition multiplied
by 20 to preserve original tile spacing. No camera-dependent scale changes.

Original GLB 27,052,900 bytes; 316,933 triangles.
Optimized interior.glb 8,357,888 bytes; 156,505 triangles.
Changes: mesh welding, boundary-preserving simplification, deduplication,
WebP quality 92. Baked background colors rendered without additional lighting.

EXTERIOR: Melbourne Street — Daniil Kulinich

Original GLB 123,024,080 bytes; optimized melbourne.glb 23,380,484 bytes.
161,824 triangles retained. Original geometry, material types and metric scale retained.
The earlier Street - Miguel de Benavides environment is no longer bundled or displayed.

Basic and exterior optimization: WebP color maps quality 90 (up to 1024px);
normal maps up to 512px and roughness/metalness/occlusion maps up to 256px,
lossless WebP encoding after resizing; deduplication and removal of unused data.
Materials remain PBR; no mesh simplification. Original files are unchanged.

All scenes receive a fixed placement transform. Floors are hidden from below;
interior architectural shells can be hidden for outside camera cutaway views.
