/* =========================================================
   REPRO İSTANBUL — Global Header / Navbar (Phase 10D, revised
   Phase 13: Süreçler dropdown + mobile hamburger drawer,
   Phase 17: logo-only home link, right-aligned nav, bold
   uppercase white menu type, description-free dropdown card,
   gap-free hover bridge)
   Fully independent: own file, own classes (globalheader__*),
   self-contained tokens (does not depend on styles.css or
   legal.css — this file is meant to be loaded, unchanged, on
   every page: the homepage and the three legal pages).
   Injected at runtime by header.js. No bracket `[...]` usage.
