/* =============================================================================
   CSDH portal sign-in — shared by the Admin, Agent and Operator login pages.

   Rebuilt from the Figma design rather than its HTML export: that export
   contains no form controls at all (the fields are empty <div>s and the button
   is a <span>), positions everything at fixed pixel offsets, and references
   twelve images that are not in the archive. The palette, typography and
   layout here follow the design; the markup is real, focusable and responsive.
