/* ================================================
   NV Design System — Reusable Component Library
   Global styles for the nv- component namespace.

   Layer structure:
     1. Design tokens   (:root --nv-*)
     2. Page header     (.nv-page-header, .nv-meta-chip)
     3. Tabs            (.nv-tabs-root, .nv-tabs-nav-wrapper, .nv-tab-btn, .nv-tab-panel)
     4. Cards           (.nv-card, .nv-card__header)
     5. Form grid       (.nv-form-grid)
     6. Fields          (.nv-field, .nv-label, .nv-req)
     7. Inputs          (.nv-input, .nv-select, .nv-errmsg)
     8. Select2 sync    (.nv-field .select2-*)
     9. Upload          (.nv-upload-grid, .nv-upload-box)
    10. Action bar      (.nv-action-bar)
    11. Responsive      (@media)

   Usage: add nv- classes in any Blazor page/component.
   ::deep is NOT needed — these are global selectors.
