/* ==========================================================================
   AL FARES "hub" — shared shell for the standalone public pages
   (sign-in, contact). Loaded by:
     resources/views/portal/hub/auth/student-login.blade.php
     resources/views/portal/hub/lms/contact.blade.php

   These pages deliberately load no Metronic bundle, jQuery or icon font —
   this file plus layouts/partials/brand-styles is the whole styling story.

   The surface tokens (--bg / --surface / --elev) are emitted per-brand in an
   inline <style> on each page, from config('brand.portal.surfaces').

   Written with CSS LOGICAL PROPERTIES so one file serves LTR and RTL.
