   Login Page – Responsive Layout with Bootstrap Grid
   ==========================================================================
   Mobile-first design with Bootstrap 5.3 Grid classes.
   
   Breakpoints (Bootstrap standard):
     - < 768px   → Mobile: stacked layout (main above aside)
     - 768-991px → Tablet: side-by-side, equal columns
     - >= 992px  → Desktop: side-by-side with optimized proportions
   
   Accessibility: WCAG 2.2 AA, focus indicators, reduced-motion support
