TITLE: Vast — A Scroll Across the Solar System FILE: 047-solar-system-scale.html === PROMPT (exact prompt used) === Create "Vast — A Scroll Across the Solar System", a horizontally scrolling journey through the solar system at true relative scale: once the Sun's width is chosen (e.g. ~600px), every distance and diameter follows from real mean values, so Earth is a few pixels across and Neptune lies an enormous scroll away. Vertical wheel/scroll maps to horizontal travel; touch swipes work; a fast-travel control jumps between planets; and a "speed of light" button auto-travels at light speed relative to the scale (Earth arrives after ~8 min 20 s — show a real-time counter). Pure black background (#000) with very minimal white type; planets rendered as small canvas spheres with subtle banding and atmospheric shading. While crossing the emptiness, poetic and factual messages appear in the void ("Most of space is this.") and an odometer shows kilometres travelled and light-time. Typography: thin sans with generous letter-spacing. Keep all facts well established (mean distances in km, diameters). SHARED REQUIREMENTS (apply to every page in this 100-page collection): 1. One standalone HTML5 file. All CSS inline in
