Tunnel engine:
- 30 speed lines (near/mid/far) rushing left→right
- 6 KPI cards at 3 depths: nearest blurry+large, far sharp+small
- Cruise speed 0.8, boost 2.5× on CTA hover
- 40% cards start in viewport for instant visual
- Motion blur: cards blur proportional to speed (0→4px)
- Glow expands & brightens with speed
Drive-the-car metaphor: hover = gas pedal, cards & lines accelerate
Like driving through a tunnel with business data flying by
