Earth seen from low orbit, built as an analytic ray/sphere in a single fragment pass. Procedural but unmistakably terrestrial: deep blue oceans, green temperate land shading to tan subtropical deserts, bright polar ice, and a swirling deck of white clouds sheared by latitude. A soft terminator sweeps day into night, where warm city lights speckle the coastlines. A pronounced Rayleigh-blue atmosphere haloes the limb, with a hot Mie forward-scatter flare on the sunward edge. Earth auto-rotates; scrolling changes the orbital altitude (apparent size), a press swells the atmosphere, and the pointer tilts the view.
