What the model said

Done. I've enhanced f7b3.html with:

1. **Dark gradient background** — Rich indigo/navy backdrop for depth
2. **SVG gradients** — Indigo-to-purple linear gradient fill with subtle stroke
3. **Dual-layer design** — Main circle + spinning glow layer with radial gradient (pink-to-purple)
4. **Animations** — Pulsing main circle (3s) and rotating glow layer (8s) for dynamic feel
5. **Visual polish** — Drop shadow, opacity transitions, refined typography
6. **Better layout** — Container wrapper for improved responsiveness, ID text anchored at bottom

The piece now has depth, motion, and visual interest while staying minimal and clean.
