/* TRAFFIC global bar — a thin institutional bar shown on top of the historical sub-sites
   (MIRAGE, CloudSurf, D-ITG, workshops, …). Everything is namespaced under .tgb and sized in px,
   because the legacy pages ship their own resets, root font sizes and element selectors.
   The bar works without JavaScript: the home link is a plain link and the compact menu is a
   native <details> element; js/traffic-bar.js only adds Escape / outside-click handling. */
