/* ============================================
   Jamie Pitts — Personal Website
   ============================================
   Apple-inspired clean aesthetic:
   light theme, single typeface (Geist), generous
   whitespace, typography-driven hierarchy, no
   colour accents — pure black, white, gray.

   Organised by:
   1. Design tokens (colours, fonts, spacing)
   2. Reset & base
   3. Layout primitives
   4. Components
   5. Responsive overrides
   6. Animations
