   EVENT EXPERIENCE — bespoke virtual-event landing layout
   (originally the old MLC site's Rethink 2026 Virtual page; now the
   reusable single-event-experience.php template, wdg-nam theme)
   Scoped under .rtx so nothing leaks into the site masthead/footer.

   Brand palette (from MLC brand guide):
     Creators Blue  #0032a0   Bright Blue  #00a9e0
     Electric Teal  #12ddb6   Electric Rose #ee448d
     Grey           #bbbcbc   Light Blue   #cceef9
   Type: Helvetica Neue LT W05 family (already loaded by the theme).
