/* ============================================================
   Fixoor Blog — Apple HIG Redesign
   
   Design Principles:
   - Glass materials with layered translucency
   - SF Pro-like typography hierarchy (weight + size, not color)
   - 8pt spacing grid
   - Spring animations with natural easing
   - System grays, restrained accent colors
   - Floating cards with minimal borders
   - iOS-native component patterns
