<p data-uix-section-desc>Six events, all on the Content part. close-* fire prewrite of <code>data-last-action</code> so eidos can tint the closing animation by causa. Each event declares its <code>family</code> (`emerge` for open/close) and intent — the sema engine maps those to per-channel signatures (sound pitch / motion / color / haptic) per the SEMA_MAP table. Click <strong>play</strong> to fire the signal on the live drawer.</p>
