/* ============================================
   ICON CUSTOMIZATION GUIDE
   ============================================
   You can easily customize icons by changing the 'content' property.
   
   Options:
   - Unicode symbols: '→', '▶', '◉', '●', '◆', '■', '▲', etc.
   - CSS shapes: Use border/background properties (see examples below)
   - Text: '@', '#', '*', etc.
   - Remove icon: Set content: '' and remove other properties
   
   For more icons, you can also use Font Awesome or other icon libraries.
   ============================================ */
