  "notes": "Grid tile of the Urban Street Kit: same 11.8 m footprint as road-intersection-4way, half of road-curve-90 (23.6 m) and a third of roundabout (35.4 m), so all of them snap to one 11.8 m grid. Tileable along X, seam edges at x = +-5.9 m. Cross-section, heights and materials identical to road-segment (carriageway |y| <= 3.75, kerb 3.75-3.9, footway 3.9-5.9). Edge lines continuous, one 3 m centre dash in the middle so both seams sit mid-gap. 12 kerb stones and 24 slabs per side; asphalt map unique to this tile and phase-matched to road-segment at both seams. Pivot on the carriageway surface (z = 0); footway +0.15 m, base -0.20 m. No bottom faces.",
