/* ============================================================
   Studio North — dark iridescent design system
   ------------------------------------------------------------
   Rules this system holds to:
     - No white surfaces anywhere. The page sits on near-black and
       the iridescent colourway runs through every section.
     - White is used for TEXT only, never as a background.
     - Radius is 0px everywhere, or a full 75px pill on buttons.
       Never anything in between.
     - No box-shadows. Separation comes from hairline borders,
       surface lift, and coloured glow.
     - All motion runs on one patient easing curve.
