FocusBackgroundimages/list-item-focus.9.pngput.io owns this
Roku focus is a footprint, not a lift. FocusBackground holds one Poster whose width and height are overwritten at runtime with the row's, then tinted by blendColor. SceneGraph lists have no z-axis, so nothing scales and nothing elevates.

Do not. Draw a focus border on a list row, or add a scale to imitate tvOS. The row's focus is one tinted bitmap; the z-axis does not exist here.
