/* ============================================================================
   GLOBAL TAB SYSTEM
   ============================================================================ 
   
   Unified tab/navigation system for all tab interfaces in Dynbrew.
   
   Design principles:
   - Icon to left, text to right (consistent across all tabs)
   - Inactive tabs: text truncates with ellipsis if needed
   - Active tab: shows full text, NO background color
   - Active indicator: colored border-bottom only
   
   Usage:
   - Base: .tabs-container + .tab-item (with .tab-icon + .tab-label)
   - Modifiers:
     - .tabs-compact     : More compact padding
     - .tabs-pills       : Rounded pill style with background
     - .tabs-minimal     : Very subtle styling
     - .tabs-wizard      : Special wizard style
   
   Example:
      <nav class="tabs-container">
        <a href="#" class="tab-item active">
          <span class="tab-icon">🍺</span>
          <span class="tab-label">Styles</span>
        </a>
      </nav>
