Fix smooth scroll easing for more consistent motion

- Changed from easeInOutCubic to easeInOutQuad for smoother motion
- Increased duration from 1.5 to 1.8 seconds
- Fixed jerky acceleration/deceleration issue
- Now provides consistent, smooth scrolling throughout entire motion

The scrolling is now properly smooth without the sudden speed changes.
