   ISEF 2026 — Registration theme
   Palette taken from the Opening Ceremony key visual: a navy -> royal blue ->
   cyan sweep lit from below, with champagne-gold accents. The KV carries no
   green, so neither does this file any more (the old teal is gone).

   The page keeps the KV's night sky. The form surface is a LIGHT card: the
   fields people actually type into sit on white at document contrast, and the
   dark sky is what frames them.
