-     * Enables preferred-size sizing interop for UIKit/SwiftUI hosting containers.
-     *
-     * When enabled, the internal container view participates in UIKit sizing APIs:
-     * - `sizeThatFits(...)` proposals from UIKit/SwiftUI are translated to Compose constraints
-     * - after each Compose layout completes, the scene is probed for its preferred size under the
-     *   latest proposal constraints
-     * - if the preferred size changes, the hosting view invalidates its `intrinsicContentSize` to
-     *   trigger another UIKit/SwiftUI layout pass
-     *
-     * This mode is intended for `ComposeHostingView` / `ComposeHostingViewController` style
-     * integrations. Other container types should keep it disabled to avoid unnecessary measuring
-     * work and potential sizing feedback loops.
+     * Enables sizing of the container to fit the preferred size of the Compose content, evaluated
+     * under the size constraints proposed by the containing UIKit/SwiftUI layout flow (e.g.
+     * `sizeThatFits` / intrinsic sizing).
