UI Toolkit for Meta Ray-Ban Display overlays and feedback

Read ../building-uit-interfaces-web/references/overlays-feedback-status.md.

Read references/overlay-components.md for component selection, ownership, event flow, and dismissal patterns.

Portal and anchor ownership

App supplies the floating portal root. Use component tooltip/menu APIs; do not portal directly to document.body or manually compute fixed coordinates.

Tooltips provide short context for an anchored target. Use them for icon-only/unfamiliar controls, not to repeat visible labels or hold essential instructions. They must track moving/scrolled anchors and choose a fitting placement.

VerticalMenu and ContextMenu are temporary focusable tooltip content—not inline layout. Use controlled state and menu item components.
