UI Toolkit for Meta Ray-Ban Display lists and menus

Read ../building-uit-interfaces-web/references/actions-lists-controls.md and ../building-uit-interfaces-web/references/screen-layout-navigation.md.

Read references/list-menu-components.md for complete row modes, popup APIs, and selection rules.

Vertical lists

If a route contains any ListItem, put the complete route flow in one VerticalList. It is the route's sole vertical ScrollView, not a section inside another page scroller.
