   Chicago Open University — admin panel theme

   Loaded after the Spike template's styles.css. Replaces the template's
   sky-blue look with the university's maroon identity: Inter type, a white
   sidebar with one accent colour, a flat top bar, bordered cards, calm
   tables and square-cornered buttons.
