   THE ONE navigation — a single top icon bar for the whole event guide.
   Marshall's 7/25 fix: the build had TWO navs (this top bar was missing, and a
   duplicate tab row lived inside each panel). Now there is exactly ONE tab
   list in the DOM — this bar — pinned to the top edge above whichever panel is
   open, matching his CREDITS/SCHEDULE mockups: dark-blue bar, icon+label tabs,
   the ACTIVE tab lit yellow. Every tab is one click from anywhere.
