/* ============================================================
   Boston (MA) Alumni Chapter - Kappa Alpha Psi
   Official Branding: Kappa Media Kit
   Design System: Apple Human Interface Guidelines (adapted)

   Apple HIG principles applied:
   - Clarity: clean hierarchy, purposeful elements
   - Deference: content-first, UI stays out of the way
   - Depth: layered surfaces with subtle shadows

   Breakpoints (Apple standard):
   - Large (desktop): >1068px
   - Medium (tablet): <=1068px
   - Small (mobile): <=735px
