/* OHMS authentication — login page styling.
   Self-contained: declares fallback values for every brand variable so the
   page renders sensibly even on apps that don't yet have the OHMS palette
   wired up. If your app already defines --ohms-*, those win.
   Drop this into wwwroot/css/ and reference from your base layout. */
