Renders true-2km district maps (derive_district per cell, NOT the coarse eager grid) as PNGs: morphology (17-zone palette transliterated from atlas_marker_overlay.gd, sync-commented), elev/temp/moisture/vegetation panels, anchor crosshair, km-honest filenames + manifest. believability.rs gains cascade_snapshot_for_body (cascade_for_body now a thin wrapper); probe re-derives the D-203-freed TerrainAnalysis via run_layer1 only under --render. Determinism proven: 5/5 panels byte-identical across passes AND cross-process (md5s reproduced in a fresh run). ~8us/district debug. First-ever look at the district layer produced the T-1125/T-1126/T-1127 findings (D-227 seam ends at ~500km; ocean-blind vegetation; unrendered glaciation).
