> At Xandora Lab, animations do not entertain. They explain.

- **micro** 150ms — hover, focus
- **element** 250ms — appear, expand
- **screen** 400ms — page transitions
- **section** 600ms — scroll reveals

If an animation does not guide attention, confirm an action, or reveal hierarchy, it should not exist.
