UI Toolkit for Meta Ray-Ban Display actions

Read ../building-uit-interfaces-web/references/actions-lists-controls.md.

Read references/action-components.md for prop-level behavior, pairings, and component-specific review rules.

Use these references before library source. Inspect one exact public type only when a selected prop remains unresolved or typecheck reports a mismatch; do not browse implementation or examples preemptively.

Selection

• Button: one immediate command.
• ButtonRail: flexible full-width horizontal lane; preferred when actions may overflow.
• ButtonGroup: small non-scrolling related set.
• ButtonDivider: logical section boundary inside a rail/group.
• QuickReplyButton: concise ready-to-send response/reaction inside a rail.
• ActionHint: visual-only instruction/continuation cue.
