   modal-core.css — UI-MODAL-LIFECYCLE-AND-ROUTE-CLEANUP-V1
   (2026-05-26)

   Canonical modal/slide-out chrome consumed by modalCore.js.
   Distinct from .emr-modal-* design-system rules so existing
   CSS-only consumers stay untouched.

   z-index slotting (REVISED 2026-07-01 — modals are TOPMOST chrome):
     10050 — backdrop  (above every drawer/overlay: settlement drawer
                        9998/9999, statementDetail backdrops 9999,
                        prefs 3000 — previously 1900/1910 buried
                        emrPrompt/emrConfirm under the settlement
                        slide-out + detail view; these are the values
                        the drawer's body.emr-stmt-drawer-open lift
                        already used, now the app-wide default)
     10060 — wrapper   (just above backdrop)
     10070 — drawer-owned prompts (statementDetailDrawer _promptOrigin)
     10100 — autocomplete dropdown (a picker inside a modal must drop
                        its list over that modal)
     99999 — toasts    (.emr-toast, preserved above everything)
