/* ============================================================
   BDE Generic Grid Stylesheet
   ============================================================
   Foundation styles for BdeGenericGrid partial view.

   Namespace: .bde-grid-*

   Provides semantic HTML table styling with:
   - Clean, modern presentation
   - Accessible rows and headers
   - Sorting and pagination UI
   - Status/progress indicators
   - Responsive behavior
   - Row state styling (active, expired, warning)

   Uses class namespacing
   to avoid collisions.
