TITLE: Planet Forge — Procedural World Generator FILE: 066-planet-forge.html === PROMPT (exact prompt used) === Build "Planet Forge — Procedural World Generator". A canvas renders a rotating sphere with per-pixel shading (ray–sphere intersection or a pre-baked equirectangular texture sampled by rotation): terrain from fractal noise mapped to biomes (deep ocean, shallows, beaches, forests, deserts, mountains, ice caps by latitude), an animated cloud layer, an atmospheric rim glow, a day/night terminator with city lights on the night side, and optional rings casting a shadow. A cosmic black background with a faint nebula and stars. A sci-fi control panel (thin lines, cyan #4cc9f0 accents, glass panels) with sliders for sea level, temperature, cloud cover, terrain roughness, ring toggle, moon count, rotation speed and seed, plus presets (Earthlike, Desert world, Ocean world, Lava world, Ice world, banded Gas giant). Each planet receives a catalogue designation (e.g. "KX-4471 b") and playful stats. Interaction: drag to rotate, "Randomize", PNG download. Keep rendering efficient (render at lower resolution and upscale smoothly). SHARED REQUIREMENTS (apply to every page in this 100-page collection): 1. One standalone HTML5 file. All CSS inline in
