Title: Totality
Exact creative prompt: Create a cinematic solar-eclipse art chamber in one offline responsive HTML. Use an almost black field, a centered glowing amber sun and movable dark moon, blurred conic corona rays, extremely spacious uppercase TOTALITY typography and tiny celestial metadata. Let a horizontal alignment slider move the moon through the eclipse and report alignment state. Keep the page minimal, dramatic and explicitly artistic rather than scientifically to scale.
Description: A single luminous celestial event fills a quiet black composition, with user-controlled alignment revealing the fragile edge of light.
Major visual techniques: Conic-gradient corona; radial glow; circular occultation; expansive tracking; near-black negative space.
Interaction model: Drag the alignment slider to move through partial eclipse, totality and departure.
