/* ============================================
   CUSTOMIZATION: COLOR THEME
   ============================================
   
   HOW TO CHANGE COLORS:
   
   1. PRIMARY COLOR (Main brand color - buttons, links, accents)
      - Change --primary to your brand color
      - Update --primary-hover to a slightly darker shade
      - Update --primary-light to a lighter shade
      - Update --primary-glow with your color at 0.3 opacity
   
   2. BACKGROUND COLORS (Dark theme backgrounds)
      - --bg-dark: Main page background
      - --bg-card: Card/section backgrounds
      - --bg-input: Form input backgrounds
   
   3. TEXT COLORS
      - --text-primary: Main text (keep light for dark theme)
      - --text-secondary: Secondary/muted text
   
   Example: To change to BLUE theme, replace:
      --primary: #3b82f6;
      --primary-hover: #2563eb;
      --primary-light: #60a5fa;
      --primary-glow: rgba(59, 130, 246, 0.3);
