Claude Opus 5.5 in a raw API call

Create a studio-quality motion graphic: the eight planets orbit a glowing sun on elliptical paths with labels. Then they leave their orbits and line up in a row sorted by size, with their relative sizes to scale-ish and a diameter label under each; then they rise back into their orbits and the loop repeats.

Requirements:
- A single self-contained HTML file: inline CSS and JavaScript only, SVG for all graphics, no canvas, no external libraries, fonts, images or network requests.
- Expressive easing (ease-in-out, overshoot, staggered delays) and true morphing: elements visibly travel between states, never a plain crossfade.
- Dark, modern design with a cohesive colour palette; portrait 4:5 layout, scaled to fit the browser window and centred.
- Motion starts immediately at page load (something is already moving in the first half second) and loops seamlessly, about 12-16 seconds per loop.
- Drive all animation with requestAnimationFrame and performance.now; no user interaction needed.
- No text beyond what the graphic itself needs (labels, values). No titles, buttons or UI.
