/* Portal-wide AI sidecar.
 *
 * This is deliberately part of the application chrome, not a floating mascot.
 * A compact top-bar control keeps it reachable everywhere; the work surface only
 * exists while the user asks for it. It follows the portal's flat, neutral design
 * language and uses elevation only for the drawer that actually overlays a page.
