The prompt

CSS Solar System: A top-down solar system in pure CSS: the sun with a pulsing corona and eight planets on elliptical-looking orbits at relative speeds, a ringed sixth planet, and a moon orbiting the third. Hovering a planet pauses it and shows its label. No JavaScript. Build it as ONE self-contained HTML file: inline CSS and JavaScript only, no libraries or frameworks, and no external requests of any kind (no CDNs, web fonts, images or audio files); anything visual or audible is made in code (HTML/CSS, SVG, Canvas, WebGL or WebAudio). It must work when opened directly from disk, fit the browser window responsively, and run without console errors. Output ONLY the complete HTML file, starting with <!DOCTYPE html> and ending with </html>, with no explanation or markdown fences.
