/* ============================================
   KAYJAH DESIGN STUDIO — Journal Archive
   Apple HIG–Inspired Design
   ============================================

   Design principles applied:
   - Clarity:    clean hierarchy, legible type, generous whitespace
   - Deference:  content commands focus, UI recedes
   - Depth:      layering via shadows, blur, translucency
   - 8pt spacing grid, 44px touch targets
   - Rounded corners (12-16px, Apple signature)
   - Purposeful, spring-based motion
   ============================================ */
