/* ==========================================================================
   Newsletter opt-in — v10 "Night Sky"
   --------------------------------------------------------------------------
   Behaviour unchanged: same fields, honeypot, time trap, consent checkbox and
   double opt-in. Only the appearance is redesigned: a dark field with a gold
   focus ring, a drawn gold checkbox and a gold pill button. One look for all
   three contexts — the front-page Star Letter panel, the sidebar and the
   modal — because every one of them now sits on the same night ground.
