  "notes": "Model origin = centre of the 23.6 m square; curve centre at (-11.8, 11.8). Seam A: x = -11.8 m, cross-section y = -11.8..0, centre line y = -5.9, traffic along +X -> place road-segment centre at (-16.8, -5.9), unrotated. Seam B: y = +11.8 m, cross-section x = 0..11.8, centre line x = 5.9, traffic along +Y -> road-segment centre (5.9, 16.8) rotated +90 deg about Z. Used as a right turn: rotate the whole tile. Both seams are identical to road-segment in geometry, height, markings (edge lines continuous; 3 centre dashes evenly spaced so both seams sit mid-gap) and asphalt texture phase. Footways in 0.5 m radial rows matching the slab rows at the seams, slabs ~0.5 m long with radial joints; curved 1 m kerb stones. Pivot on the carriageway surface (z = 0); footway +0.15 m, base -0.20 m. No bottom faces.",
