# Nothing Design System — Motion & Interaction

- **Duration:** 150-250ms micro, 300-400ms transitions
- **Easing:** `cubic-bezier(0.25, 0.1, 0.25, 1)` -- subtle ease-out. No spring/bounce.
- Prefer opacity over position. Elements fade, don't slide.
- Hover: border/text brightens. No scale, no shadows.
- No parallax, scroll-jacking, gratuitous animation.
