/* ============================================
   KAYJAH DESIGN STUDIO — Single Journal Article
   Apple HIG–inspired: clarity, depth, deference

   Principles:
   - Content commands focus, UI recedes
   - 8pt spacing grid, generous whitespace
   - Reading-optimised typography (65–75 ch)
   - Spring-based, purposeful motion
   - Frosted glass & layered depth
   ============================================ */
