/* ============================================================
   The Meridian Summit — Business Conference CARD (invitation)
   template/creative/html/business-conference-card-meridian-summit
   ------------------------------------------------------------
   Design language: a premium printed invitation. Warm ivory paper
   with a subtle linen weave, double hairline gold plate, editorial
   serif letter, and a detachable "reply card" RSVP section.
   Everything is drawn in CSS — zero image files required.

   Behaviour:
   - Continuous scroll: every section (panel) is stacked in the normal
     document flow and the page scrolls from one to the next. Nav tabs
     and CTA buttons smooth-scroll to their section; a scroll-spy keeps
     the active tab in sync. Tabs derive from the DOM, so removed
     sections hide their tabs.
