/* =============================================================================
   Unified Modal Shell
   Single source for the shared .modal lifecycle host used by all customer
   modals (prepare-to-ship, increase-bid, address, confirm). Content-specific
   rules live with their own feature CSS; only the generic shell + size
   variants belong here.

   The host node (modal-system.js) carries `luna modal` itself, so rules match
   `.luna.modal` (compound): in wp-admin there is no body.luna ancestor and the
   host is the token root.
