   Same brand identity (deep navy · signal blue · gold), re-cast as a premium
   dark-aurora + frosted-glass dashboard. The signature is preserved and
   elevated: "The Path" — a luminous thread that draws itself on login and
   becomes the glowing spine of the program timeline.

   Material rule (keeps arbitrary admin HTML readable):
     • chrome & dashboard  -> dark glass  (light text)   .sp-glass
     • dense rich content  -> frosted paper glass (dark)  .sp-paper-glass
