/* ==========================================================================
   Kalcom Academy — shared "ZSHT-style" interface theme
   One file, included by every portal (tenant app, super admin, parent
   portal) instead of each page redefining its own <style> block. Mirrors
   the ZSHT school system's visual language:
     - dark gradient navbar with Font Awesome icons + dropdown nav groups
     - gradient hero/page header banner
     - white rounded "stat card" tiles with icon + big number + label
     - lift-on-hover dashboard cards
     - a "quick actions" panel
