/*
 * ============================================
 * Authentication Pages Unified Styles
 * ============================================
 * 
 * Purpose: Provides consistent design and animations for all authentication pages
 * Applies to: Login, Register, ForgotPassword, ResendEmailConfirmation, Logout, etc.
 * 
 * Usage: Include this stylesheet in @section Styles { } of any auth page:
 *   <link rel="stylesheet" href="~/css/auth-pages.css" asp-append-version="true" />
 * 
 * Key Classes:
 *   - .login-container: Main container with background gradients and animations
 *   - .login-form-section: Card/form container with shadow and hover effects
 *   - .form-group-animated: Animated form groups with staggered entrance
 *   - .MainButton: Primary action buttons with hover effects and loading states
 *   - .login-links: Links section with hover animations
 * 
 * Architecture: Separate from site.css for:
 *   - Performance (only loaded on auth pages)
 *   - Maintainability (dedicated auth styles)
 *   - Modularity (easy to update all auth pages at once)
 * ============================================
