The .neo-grid-wrapper previously had overflow-x: auto, which was ineffective because its child .neo-grid-container is absolutely positioned. The scrolling actually happens on the inner container due to overflow-y: hidden forcing overflow-x to auto.

To make this behavior explicit and less fragile:

1. Remove overflow-x: auto from .neo-grid-wrapper.
2. Add overflow-x: auto to .neo-grid-container.

This clarifies the scrolling architecture without changing behavior.
