Planet Window — 3D Space Landing Page

A complete, scrollable space landing page with the 3D built into it: pick any of eight planets and watch it turn in a porthole above its own horizon. It is one self-contained HTML file, built entirely in code, with no image files, no 3D models and no build step. Under the hood: Three.js, one full-screen shader: ray-traced sphere with noise surfaces, bands, clouds, ice caps and rings, plus a layered horizon, eight planet presets blended live. What a visitor can do: click a planet in the list, scroll to open the window into space, move for parallax, dock shortcuts (Mars, Earth, Saturn, Neptune). Best for: Space and science brands, museums and planetariums, education, sci-fi games and films. Three.js loads from a CDN through an import map and the type (Anton, Inter) from Google Fonts, so there is still nothing to install. The page is real HTML — a navigation bar, a full-height hero, content sections, a call to action and a footer — so the brand name, headlines and cards are edited as plain text. Colours, counts and speeds sit in a CONFIG block and a PRESETS array, colour themes restyle the page and the 3D together from a small swatch pill, ?embed hides the pill and ?tour scrolls the page by itself.
