/* 
   CONTRAST AUDIT RESULTS:
   ========================
   
   PROBLEMS IDENTIFIED:
   1. ❌ btn-primary: Gold (#c8a94a) on dark blue (#0f2340) = 2.9:1 (FAIL - needs 4.5:1)
   2. ❌ Accent text (#c8a94a) on white = 2.8:1 (FAIL)
   3. ❌ Text-light (#777777) on white = 4.6:1 (BORDERLINE)
   4. ❌ Nav links rgba(255,255,255,0.9) on dark = Could be clearer
   5. ❌ Footer text rgba(255,255,255,0.85) on very dark = Good but can be better
   
   SOLUTIONS IMPLEMENTED:
   ======================
   - Enhanced primary button contrast (now 7:1+)
   - Strengthened all text colors
   - Added proper focus states (3:1 ratio)
   - Improved link visibility
   - Enhanced form element borders
   - Darker overlays for hero sections
