Scroll focused tile into view

React chapter 131 · TV / rail paging · source: Spatial carousel (78) · Element.scrollIntoView

The problem

The D-pad updates (row, col) but the rail never scrolls. Focus walks into cards you cannot see. A living-room remote has no trackpad — the focused poster must bring itself on-screen.

The pattern that fixes it

When the focused cell changes, call scrollIntoView on that node (inline: center). Netflix-style rails page with the focus, not with overflow-x plus a mouse wheel.
