/* ==========================================================================
   NEPHBOX SHARED COMPONENTS
   --------------------------------------------------------------------------
   Baseline styling for the UI vocabulary that recurs across pages: surfaces,
   buttons, form controls, tables, modals, badges, focus states.

   Load order matters:  tokens.css -> components.css -> <page>.css
   Page stylesheets load last and therefore win on equal specificity, so a
   page can still override anything here without !important.

   The glass treatment used to live only in dashboard.css, which meant the
   dashboard looked like frosted glass while library/gameservers/suggestions/
   support/admin used flat opaque panels. It is defined once here and applied
   to every recurring surface.
