/* ==========================================================================
   Nav dropdowns / mega-menu — added for the full-sitemap build-out.
   Kept in its own file (layered after styles/global/home.css) so it stays
   separate from the design's CSS and is reversible. The design shipped
   `.has-mega` items with only a chevron; these panels add the child links.
   Desktop = pure-CSS hover/focus reveal (no JS). Mobile = shown when main.js
   toggles `.mm-acc.open` (its existing accordion handler).
