- Chunk stores per-section biome arrays (64 cells/section); flat generators keep the uniform single-valued fallback. - New writeBiomePalette uses min 1 bpe and direct at registry width (65 biomes). - Climate sampler splits 2D axes (sampled once per column) from 3D depth (per cell), keeping per-cell cost to a single density-function compute. - Full biome parameter table (surface + underground twins + lush/dripstone/ deep_dark caves) with depth as a true range, not a binary layer. - fillBiomes3D fills the 1536 cells/chunk in parallel; <0.3ms overhead vs baseline chunk gen (benchmark-verified). - Tests: cave-biome resolution, per-cell variation, flat-world regression, registry-range validity, plus chunk-gen and per-cell benchmarks.
