/* =========================================================================
   NYU Archway - interface stylesheet
   =========================================================================

   Hand-written, no build step, no framework. Every value that varies between
   light and dark is a custom property on :root and is redefined twice below:
   once under prefers-color-scheme for the OS setting, and once under
   [data-theme] for the in-app toggle, which must win either way.

   NYU violet (#57068c) is the accent - it marks the one primary action on a
   screen, the active nav item and the focus ring. It is deliberately NOT a
   chart colour: a hue that means both "NYU" and "the Gemini series" is read
   wrong every time.
