/**
 * COEUS Design System - Login Page Components
 *
 * PURPOSE:
 * Styles for the login/authentication page including passkey registration
 *
 * COMPONENTS:
 * - .login-container - Full-height container for login card
 * - .login-card - Glassmorphism card with form
 * - .login-logo - Logo container (displays COEUS.png without background)
 * - .passkey-button - Primary action button for passkey auth
 * - .form-input - Input field styling
 * - .notification - Toast notification system
 * - .notification-icon-* - Theme-aware notification icon colors
 * - .code-input - 6-digit verification code inputs
 * - .divider - "oder" separator with horizontal lines
 *
 * DEPENDENCIES: core/variables.css, core/themes.css
 * LAST UPDATED: 2025-11-23 - Theme-Aware Color Fix:
 *               - Replaced var(--ios-label) with var(--text-primary) for theme responsiveness
 *               - Added .notification-icon-success/error/info classes using iOS system colors
 *               - All text now uses theme-aware variables (works in light & dark mode)
 *               - Fixed .login-title and .code-input to use var(--text-primary)
 *               - Removed all hardcoded color references
 *               V2 Styling Fix (2025-11-23):
 *               - Removed orange gradient background from .login-logo
 *               - Fixed logo to display COEUS.png properly with object-fit: contain
 *               - Fixed .divider spacing to 2rem (32px) top/bottom
 *               - Removed duplicate .divider definition (CSS cascade conflict)
 *               - All styling uses CSS classes only (no inline styles)
