/* =========================================================================
   Murugan PVC Pipes — Site header v4
   Hand-written, scoped to .mpp-head. Loaded site-wide (the header renders on
   every page), after assets/home.css.

   The utility bar, the sticky bar and the mobile drawer are SIBLINGS rather
   than children of one wrapper: `position: sticky` is constrained to its
   parent's box, so nesting the bar inside a short wrapper let it stick for
   only ~40px before scrolling away. Each root carries .mpp-head, so the
   shared tokens and descendant rules below apply to all of them.
