/**
 * ACE All Courses
 *
 * The homepage's system -- same tokens, same buttons, same cards -- scoped
 * to .ac so nothing here can reach another page. Each programme adds one
 * accent (--acc) for its badge, its drawing and its glow; the buttons stay
 * the site's teal.
 *
 * Rules carried over from the homepage, because the site has paid for them:
 *   - anything given a display value also gets an explicit [hidden] rule;
 *   - text in teal uses the lighter teal, white text sits on the deeper one;
 *   - nothing is left invisible if a script fails: undrawn and unrevealed
 *     states only apply under .ac-js, and .ac-show (a failsafe set from
 *     <head>) undoes them.
