/*
 * Phase 4 Checkout stacking closeout.
 *
 * MBCO intentionally raises interactive block-workflow host children to z-index 60
 * while excluding the registered universal outer-frame carrier from that content
 * layer. Checkout header/body backgrounds extend flush to the panel perimeter, so
 * the canonical base carrier z-index 20 is visually occluded on this consumer.
 *
 * Live reversible proof established z-index 61 as the minimum layer above Checkout's
 * MBCO content plane. Keep this override exact to checkout-drawer only.
