/* DeepDrft Global Styles - Simplified & Maintainable

   Note: the palette / token layer (--deepdrft-*, --theme-*, --gradient-*, and the
   .deepdrft-theme-dark override block) lives in DeepDrftShared.Client and is
   served at _content/DeepDrftShared.Client/styles/deepdrft-tokens.css. Link that
   file BEFORE this one in App.razor — every rule below depends on those tokens. */
