/* ==================================================================
   UNYKORN MINT — light, dimensional, glass.

   The look: a pale studio ground with real depth. Panels are glass that
   actually samples what is behind them, lit by a specular rim that tracks the
   pointer, sitting above a soft contact shadow. Nothing is a flat card with a
   border.

   Layer order is declared once so nothing needs !important and no BEM.
