<%# Markup for the clipboard (copy & completion feedback) demo.
    Copies via navigator.clipboard and announces completion in a role="status" live
    region. For localization the completion messages are passed via the copied-label /
    error-label Values. The look per data-state (idle / copied / error) lives in demo.css. %>

// Consumer-side JS for the clipboard demo (optional).

// detail { success, text }. The consumer subscribes to add its own behavior
// (analytics, a toast, etc.) — here just a simple log.
