/* =====================================================================
   FF Header Nav v1.0.0 (2026-09-18, Sarah + Claude)
   Dropdowns + Teacher Tools mega menu for the site-1 primary menu.
   Loaded by the "FF Header - mega menu" snippet, which swaps the theme's
   Bootstrap navwalker for FF_Mega_Navwalker on teacher-door pages.
   Every class here is prefixed ffn- (no Bootstrap-reserved names).
   Brand: navy #001b72 (matches the live header buttons), teal #00b09b,
   gold #ffc107, teal tint #e8f8f4, lavender #f4f1ff.
