/* ==========================================================================
   CSE 2407 Grade Calculator

   The page is built around one picture: thirty slots, one per point, grouped
   by the goal or exam that fills them. Everything else stays quiet so that
   bar carries the weight.

   Status colours (P / D / S) were checked for colour-vision separation
   against both surfaces; every coloured mark also carries its letter, so
   colour is never the only signal.
