/* ============================================
   RUBI Blockchain - Shared Styles
   ============================================

   This is the shared CSS foundation for all RUBI node applications:
   - BC.SentinelNode (green theme)
   - BC.PermanentNode (blue theme)
   - BC.UP.ExchangeClient (ruby/rose theme)
   - BC.MerchantNode (amber theme)
   - BC.AdminDashboard (purple theme)
   - BC.PaymentPortal (ruby theme)

   Each app should:
   1. Include this file first: <link href="css/rubi-shared.css" rel="stylesheet" />
   2. Then include app.css which overrides --theme-* variables

   ============================================ */
