Exact through LOD2 (all near tile hashes equal L82). W8 LOD0-2: SW 1.09->1.06, FI 2.47->2.34, TN 2.39->2.43 (noise), VS 1.20->1.18 s. Fast tier PASS. Scaling W4/W8/W12/W16 (LOD0-2, FI): 3.59 / 2.48 / 2.33 / 2.34 s - flattens past W8-W12. Estimated infinite-worker floor ~1.0 s FI/TN = shape compile (0.35-0.41 s, not overlapped: no shape-free tiles in these views) + slowest single LOD0 tile service (0.51-0.59 s).
