/* ---- Signed-out backstop ----------------------------------------------------
   WHY: every overlay in this app lives OUTSIDE <main id="app-main-shell">, so the
   auth gate — which only hides that shell — cannot hide any of them, and
   `.modal { position: fixed; inset: 0; z-index: 999 }` puts each one squarely over
   the login form. Eight of twelve stayed up through a user change, one of them the
   full rendered quotation (client details, line items, prices, totals, bank details).

   App._closeOutgoingUserSurfaces() closes them properly — settling the promises that
   two of them hold, which CSS cannot do — and this is the SECOND line of defence
   behind it, not a replacement: if teardown ever misses a surface again, the surface
   is still not painted over the next rep's login screen. Keyed on the class, not on a
   list of ids, so a new modal is covered the day it is written.

   App._enforceAuthGate() puts is-signed-out on <body> whenever nobody is signed in. */
