/* =========================================================
   SAP Device Type DB — UI design language
   =========================================================
   Adopted from BECONEX AIProcessor (gitrepos/aiprocessor/src/wwwroot/app.css).
   Same `ocr-*` class prefix kept on purpose so the look-and-feel is
   recognisable across BECONEX products. Custom DTDB-only pieces use
   the same prefix to avoid divergence.

   Uses SAP CSS variables (--sap*) from UI5 Web Components for theme
   coverage; literal fallbacks for the standalone draft.
