/* AP CS teaching site — shared design system.
   Load it LAST in <head> so it wins over each page's older inline rules:
     <link rel="stylesheet" href="/site.css">
   site-nav.js adds it for any page that forgot.

   Tokens first, then the primitives every page already uses by name —
   .topnav, header.top, .card, .btn, .row, label.fld, inputs — so a page
   picks up the new look before a line of its own CSS is touched. Page-
   specific pieces (seats, schedule rows, chips) keep their own rules and
   read these tokens.

   Hue: the classroom tools (seating, picker, insights) run violet, the desk
   tools run blue. A page sets it with <body class="hue-violet">; blue is the
   default. */
