/* ============================================================================
   IMSS HEALTHCARE — ENTERPRISE PREMIUM CSS SYSTEM
   
   This is a complete redesign incorporating:
   - Healthcare enterprise color palette (#1B5E85 primary navy, no burgundy)
   - Serif typography for premium positioning (IBM Plex Sans headings)
   - Modular spacing system (4px base scale)
   - Unified component library
   - Premium shadows and depth
   - Clinical, trustworthy aesthetic
   - WCAG 2.2 accessibility standards
   - CONSISTENT HOVER EFFECTS across all interactive elements
   
   ============================================================================
   HOVER EFFECT CONSISTENCY RULES:
   - All hover transitions use: var(--transition-base) var(--cubic-ease)
   - All interactive elements have unified hover timing (0.22s)
   - Color changes: navy primary (#1B5E85)
   - Transform patterns: translateY(-2px to -10px), translateX(2px), scale(1.02)
   - Background colors use rgba navy at 0.04-0.08 opacity
   - Cards/larger elements: -6px to -10px translateY
   - Small elements: -2px translateY
   - Links: add light background or slight color shift
