/* ============================================================
   Internships — visual system

   One accent hue (green) carries every interactive and data
   mark. The Statistics bars are a single-series magnitude
   chart, so they use one hue at varying emphasis rather than a
   categorical palette — which sidesteps colorblind-adjacency
   problems entirely instead of trying to pass them.

   Dark mode is chosen, not flipped: its surfaces sit slightly
   warm, and the accent lifts in lightness so it still reads
   against a dark ground.
