/* ═══════════════════════════════════════════════════════════
   CreditPlanner.in — styles.css (Part 3 — refreshed theme)
   
   WHAT CHANGED from Part 1/2:
   - Base bg lifted from #0c0c0e → #141416 (softer, less harsh)
   - Card surfaces lifted for better depth perception
   - Text contrast improved — secondary text is more readable
   - Borders slightly more visible
   - Status colors slightly brighter backgrounds for readability
   - Accent shifted warmer (less neon purple, more refined indigo)
   
   Aesthetic: Soft dark — like Linear, Vercel dashboard, Raycast
