 * Lease only these two host prototype methods while a Fabric overlay is open;
 * native layout, focus, visibility, image deletion and upload caches still own
 * the frame. Resolve through the supplied live proxy, never import another TUI.
 * Background layers deliberately hide images rather than trying to z-order
 * terminal graphics against text. The native diff restores them on close. */
