/**
 * login.css — AIShala Login Page · Responsive Enhancement
 * =======================================================================
 * Depends on: style.css (design tokens)
 *
 * Key responsive changes:
 *  • Mobile (< 768px): full-width single-column, image panel hidden
 *  • Tablet (768–1023px): narrow form panel, still single column
 *  • Desktop (1024px+): two-panel split layout restored
 *  • Fluid padding, font sizes, button heights
 *  • Login card max-width prevents over-stretch on 4K
 * =======================================================================
