Requirements

Node	22.23.2 or a newer supported LTS release; .nvmrc records the tested version
Browser	one with WebGPU enabled, for example a current Chrome or Edge on the desktop
GPU	a discrete GPU is strongly recommended: the engine renders a whole planet with shadows, atmosphere, clouds and vegetation. On first load the game measures the machine and picks one of three graphics presets (High, Medium, Low); see “Graphics presets” below.
Disk	about 2.5 GB for the checkout, the assets (about 2.2 GB) and node_modules (about 150 MB). The download cache adds about 2.2 GB until you delete it, and npm run build writes about 2.2 GB to dist/
GitHub CLI	gh, signed in, to download the asset bundles: https://cli.github.com

Rust is not required. The physics WASM ships prebuilt.
