Full terrain-to-render pipeline at tooling/planet-gen/: - body_definition_parser: reads system index.md → body definitions - planet_simulation: FBM + Voronoi ridges, Whittaker biome classification, D8 river routing, physics-driven craters (atmo × tectonics scaling) - render_heightmap: 4096×2048 cartographic maps with hillshade - planet_renderer: 512×512 globe with terrain UV mapping, clouds, rings - biomes.toml: externalized color/classification tables (single source) - scaffold_bodies: creates per-body index.md with YAML frontmatter - batch: unattended processing with error handling, resume, determinism check Supports all body types: temperate, arid, frozen, volcanic, barren, oceanic, gas giant (banded + ringed), and moons (half-size, grey, cratered).
