Guidance for accessible user notifications and feedback. AUTO-TRIGGER when implementing: toasts, snackbars, notifications, alerts, flash messages, status messages, success/error feedback, or any transient UI messages.

Use this skill BEFORE implementing any toast-like patterns to ensure accessibility compliance.
