<%# Markup for the clipboard (copy & completion feedback) demo.
    Copies via navigator.clipboard, shows the result in the visible feedback slot,
    and hands the announcement to the shared stimeo--announcer your app seats once,
    in its layout. Keep the feedback slot free of live-region semantics — the
    announcer already reads the result, so a role="status" here would say it twice.
    For localization the visible labels come from the copied-label / error-label
    Values and the spoken ones from the announce-copied-text / announce-error-text
    Values. The look per data-state (idle / copied / error) lives in demo.css. %>
