/* ============================================================================
   Klar editing blocks (frontendlib/Components/Klar/Editing, README.md there):
   identity header, attention strip, tabs, banners, editor layout, save bar,
   review dialog, guided flow, matrix.

   Linked right after assetmanager.frontend.styles.css in both host pages.
   Colour comes only from --mud-palette-* and --klar-* tokens, so every theme
   (Klar, Nucera, Purple, Default, Yeti) and dark mode work without changes.
