   USAGE INSTRUCTIONS:
   
   1. All widgets must declare a dependency on this CSS file
   2. Use --bith-widget-* variables instead of hardcoded values
   3. Inherit base classes (.bith-widget-card, .bith-widget-btn, etc.)
   4. To override values per widget, use the local variables --_widget-*
   
   USAGE EXAMPLE IN A WIDGET:
   
   .bith-my-widget {
       --_widget-primary: var(--bith-widget-secondary); // Change primary to secondary
       --_widget-radius: var(--bith-widget-radius-md);   // Use smaller radius
   }
   
   .bith-my-widget .card {
