   ADMIN_RESPONSIVE_v1  (2026-07-12)
   ---------------------------------------------------------------------
   The super-admin console had ZERO media queries — it was desktop-only and
   broke on tablets/phones. Like the tenant SPA it is built almost entirely
   from inline styles in admin.js (17 modals with .modal-bd/.modal, most
   carrying an inline max-width), so class rules must use !important to win.

   Additive + reversible: delete this block to fully undo.
