/* ==========================================================================
   ETS Nav Menu
   Layout mode is driven by [data-mode]:
     - absent / "mobile"  -> hamburger + off-canvas accordion drawer
     - "desktop"          -> horizontal bar + hover/focus dropdowns
   Default (no JS) falls back to the mobile branch so mobile never sees the
   long expanded list.
