🪐 Procedural Planet: Climate, Biomes and Sea-Level Lab

Generate a noise-terrain planet and watch its climate emerge: annual insolation from axial tilt, a 6.5 K/km lapse rate, Hadley-cell rainfall bands with orographic rain shadows, Whittaker-diagram biomes and ice caps. Sliders for tilt, ocean fraction (sea-level percentile), gravity (peak height scales as 1/g), stellar flux and greenhouse warming, on a 2D map and a 3D globe.
