/* NY Penn departures -- one page, no build step, no framework.

   THE ONE COLOUR RULE THAT MATTERS: a posted track is neutral/black and a
   predicted track is green. Those two must never be confusable, because the
   difference is "NJ Transit said so" versus "we think so". In dark mode
   "black" becomes the high-contrast foreground rather than literal black --
   the point is authority versus estimate, not the specific pigment. */
