   Mobile (base):

     - Search lives in the header as a dedicated round button that
       reveals a slide-down input bar.

   Desktop (≥768px):
     - Bar sits low-left with labels visible, dividers between groups,
       and an inline search input popping above its button.
     - The header search button + slide-down bar are hidden.
     - The filter dropdown is an absolutely-positioned popover above
       its trigger button.

   Breakpoint: only one — @media (min-width: 768px).
