/* ───────────────────────────────────────────────────────────────
   Forge nav — grouped dropdown menus.
   Extends the base `.forge-nav` in forge.css with submenu groups, so
   the top bar can be decluttered from a long flat link list into a
   few labelled dropdowns (Performance, Ecosystem, Community, …).
   Uses only existing Forge tokens; no new colors.
