/* =====================================================================
   MI SHELL — Design Lock V1 application shell.
   Owns: top navigation, brand, global search, More menu, header actions,
   mobile bottom navigation, modal chrome, app-wide focus baseline.
   The legacy shell selectors were removed from the older stylesheets in
   the same change (see docs/design-lock/legacy-shell-migration-manifest.md), so
   these rules apply without !important.

   Hooks are the existing IDs / classes / data-view attributes used by
   app.js, healthtech-ui.js, clinic-os-v286.js and clinic-os-v287.js.
   Nothing here changes navigation logic.
