/* ==========================================================================
   Sangati Medika - Healthcare Portal login

   Split light/dark: a dark hero panel carries the photograph and the brand
   message, the form panel stays light so that label and input text is
   legible on cheap screens, in sunlight, and for older patients.

   Colour tokens come from public/css/brand.css. Do not hardcode hex values
   here; add a token there instead so the portal and the MCU system agree.
