Orbital engine:
- 8 KPI cards on elliptical orbits (rx:320-380, ry:100-140)
- Cards rotate around center — appear on left/right edges
- Visibility = |cos(angle)| — brightest at sides, fade toward center
- Scale: 0.6–1.0 based on horizontal position
- 60 radial lines from center outward (forward motion feel)
- Glow pulses & expands with speed
- Center: clean headline + CTA (composio.dev style)
- Hover = accelerate orbit speed (CRUISE 0.4 → BOOST 3.0)

No more dots, no falling snow — coherent orbital dance around the text
