All four road tiers now carve into the 3D world. Rugged and Trail were generated, exported and parsed all along, but nothing ever consumed them — which is why county roads visible on the 2D map did not exist in 3D. Tier identity is now carried into the carve via a RoadSegment struct, so each tier gets its own width, shoulder and grade-smoothing from one tunable block in Constants: highways widest and holding a grade, trails narrow and hugging the land. Rugged and Trail surface as dirt rather than asphalt. Because tiers now have different reach, nearest-by-distance was no longer a sound way to pick the governing road — a nearby footpath could shadow a highway whose shoulder still covered the column. The carve now considers only roads whose shoulder actually reaches, and takes the closest of those. The per-chunk cull pad is derived from the widest shoulder plus a margin, so widening a road cannot silently truncate it at chunk edges. Untouched: density field, Marching Cubes interpolation/welding, chunk dims, the .dat contract, the 2D A* generation, and mesher normals.
